Intermittent VM Heap crash during hot-reload since Flutter 3.10/Dart 3.0 #126884

slightfoot · 2023-05-15T21:47:26Z

Is there an existing issue for this?

I have searched the existing issues
I have read the guide to filing a bug

Steps to reproduce

I am afraid I cannot reproduce with consistence, just every so often a hot-reload will crash with the reported log. Clean builds do not make a difference.

Expected results

Not to crash on hot-reload

Actual results

Crashing and application termination during hot-reload.

Code sample

No code available. This is not a framework issue. Rather a Dart/Engine issue.

Screenshots or Video

No response

runtime/vm/heap/become.cc: 293: error: become: Cannot self-forward

/cc @rmacnak-google

I am afraid I cannot reproduce with consistence, just every so often a hot-reload will crash with the reported log. Clean builds do not make a difference.

Without reproduction this will be hard to diagnose. If you find a way to reproduce this (even if just with some probability) that would help a lot

johannesvuorinen · 2023-05-16T08:24:30Z

Happens in our app as well. In my case happened 10/10 when added (while app was running) Widget? wid; as member to StatefulWidget and then in build() returned that wid if not null - otherwise assign to that wid member the widget to be returned from that build(). When hotreloaded with those added code it crashed.

I am running M1X Mac with rosetta

Hi @johannesvuorinen, can you provide a minimal reproducible code sample since you're also experiencing this?

spkersten · 2023-05-16T14:00:12Z

Happens also in our app. Not sure how to reproduce it.

Happens in our app as well. In my case happened 10/10 when added (while app was running) Widget? wid; as member to StatefulWidget and then in build() returned that wid if not null - otherwise assign to that wid member the widget to be returned from that build(). When hotreloaded with those added code it crashed.

Tried this out with a flutter create example. Adding Widget? wid to MyHomePage (StatefulWidget subclass) and then make the corresponding _MyHomePageState (State subclass) return return widget.wid ??= <...old code>. Though that doesn't reproduce it.

@johannesvuorinen If you have a 10/10 success rate reproducing it, could you try to make a minimal reproduction that can be shared?

@rmacnak-google has a speculative fix here https://dart-review.googlesource.com/c/sdk/+/303860, this should roll into the latest flutter builds in a day or two, @johannesvuorinen in case you are not able to produce a minimal reproduction would it be possible for you to try your current app on the latest flutter version that would have this change to see if it fixes your problem.

johannesvuorinen · 2023-05-23T06:13:33Z

So far seems good. I built custom engine for mac debug with the dart sdk revision containing that change.

johannesvuorinen · 2023-05-23T13:10:05Z

Multiple team members confirming that the hot reload crash is not happening anymore with the newer dart sdk revision.

@itsjustkevin this could be a potential candidate for cherry pick into stable, will file a cherry pick request on the Dart side

itsjustkevin · 2023-05-23T20:19:57Z

Thanks for tagging this @slightfoot and thanks for bringing it to my attention @a-siva.

I am going to remove the cp:review label as to not interfere with triage. Standing by for the cherry-pick solution.

Hello people i am facing same issue when hot reloading and or when switch index in bottom navigation( not official bottom navigation but custom made bottom navigation bar with row and container) but it started happening all of sudden. it was working just fine any temporary workaround for now? thanks! 👍

VirtualAstronaut · 2023-05-29T06:54:53Z

@mkustermann Hello i think i have example that makes VM crash please take a look.
Thats _LeaveDataView is in column and when i don't wrap it with Expanded it crashes VM.

mkustermann · 2023-05-30T10:34:23Z

@VirtualAstronaut It seems to me that the example you provided goes into an infinite loop, consuming 100% CPU and RAM consumption goes continuously up. The reason is that creating the list will make it go into an infinite loop:

          child: ListView.builder(
            shrinkWrap: true,
            itemBuilder: (context, index) {
              return _LeaveTile();
            },
          ),

=> The itemBuilder closure should return null at some point - depending on the passed index.

So this seems unrelated.

I am able to reproduce this issue. It happens a lot.

I have two Flutter projects, one called fishm, the other one called fishm-packages. fishm is a runnable Flutter projects, it uses some packages which are defined in fishm-packages. When I change code in fishm-packages, if I do hot reload in fishm, it crashes. This only happenes after I upgrade to Flutter 3.10.2

mkustermann · 2023-05-31T07:30:05Z

I am able to reproduce this issue. It happens a lot. ...

Firstly, could you try with flutter master channel to confirm it still happens in newest flutter?

If so, please provide precise instructions on how to reproduce the issue - otherwise we won't be able to diagnose the root cause.

zanderso · 2023-06-05T17:36:10Z

dart-lang/sdk@b28ac57 is now available in Flutter 3.10.3.

a-siva · 2023-06-05T17:40:23Z

@qtldleon can you try your application with Flutter 3.10.3, thanks.

Hixie · 2023-06-06T22:37:37Z

@slightfoot If you've been able to see this it would also be good to know if you can reproduce this with 3.10.3 (even if it's not reliably).

FlippedOvO · 2023-06-07T08:44:51Z

still in 3.10.3

a-siva · 2023-06-07T17:21:07Z

@FlippedOvO looks like the issue you are running into is different from the one originally reported here by @slightfoot .

Can you open a new issue and provide us with some reproduction instructions so we can investigate it.

FlippedOvO · 2023-06-08T03:39:33Z

@FlippedOvO looks like the issue you are running into is different from the one originally reported here by @slightfoot .

Other than the error received, everything is the same as the problem, including the operational steps.

spkersten · 2023-06-08T07:51:15Z

I haven't seen any crashes on hot reload anymore after upgrading to 3.10.3

chinmaygarde · 2023-06-12T17:42:44Z

@a-siva From Triage: Seems like we can close this as fixed in 3.10.3. Is the issue reported by @FlippedOvO tracked anywhere or are we repurposing this issue to track their observations as well? I'd prefer the former.

a-siva · 2023-06-13T16:57:21Z

I have asked @FlippedOvO to open a new issue but I don't believe he has done it yet. We should not repurpose this issue to track that issue, I would prefer a new issue with a reproduction is opened.

mjablecnik · 2023-06-14T11:25:06Z

I had same error as @slightfoot described in main description. And after update Flutter to latest stable version 3.10.4 I don't see the error anymore.
So I think that error is solved right now :)

qtldleon · 2023-06-19T03:19:20Z

@qtldleon can you try your application with Flutter 3.10.3, thanks.

Sorry I didn't get change to try with Flutter 3.10.3, but I tried with Flutter 3.10.5. With 3.10.5, I didn't see any same crash. Thanks for fixing this issue.
