[aiqinxuancai]

We use the OC version of Protobuf 3.12.0 which is install by pod.

According to the collected crash logs, the problem only occurs on 32-bit devices such as iPhone5, iPhone4s, iPad4, and iPadMini.

This sounds like what was fixed in #6678 last year.

What version of Xcode? Are you sure you are getting 3.12.x protobuf? Can you make a simple repro project that shows the issue?

[thomasvl]

From your call stack, GPBCodedInputStream.m:134 lines up with a valid line from before the mentioned fix. Looking at the sources in the 3.12 release, that line number does not match. So it does seem to indicate you aren't using the 3.12 release and using someting older that does have the bug.

Sorry, I made a mistake.

It has been confirmed that there is no crash when using version 3.12.0, which seems to be caused by Jenkins not being updated to the latest version in time.
