assertion failed: prev.ref_count() >= 1

[lifeRobot]

Version
tokio 1.36.0

Platform
Windows 11

Description
error msg:

I don't know which part of the code is problematic, but my program is experiencing panic!
this issue like #6402

Is it also because tokio::select! was used in the loop

That assertion isn't supposed to fail. Can you share some code that triggers it?

We have a similar issue, haven't narrowed it down to a reproducer yet, but our service is open source & I've added links to the call site into our tracking ticket here: neondatabase/neon#7162 . I don't know that it's all that instructive, but we hadn't seen this exception before adding that particular piece of code.

@jcsp @lifeRobot what rust versions were you on when you saw this?

[Darksonn]

Please move discussion to #6424.

@lifeRobot please hop over to the new issue if you can, we are looking for more information from folks to try and narrow down what it might be.
