Observed crash on iOS, need help

[Tao Cui]

hi,

We observed a few crash after we integrated cronet into our app for iOS platform:

based on the crash stack, it crashed when trying to detach the same thread twice?

Do you think it's normal that the same thread was detached twice?

Regards,

Tao

Can you file a bug at https://bugs.chromium.org/p/chromium/issues/list with more details? (Then reply here with the link).

PlatformThread::Detach() doesn't make a recursive call so I wouldn't trust that part of the callstack.

Likely it is hitting an assertion failure due to pthread_detach() not returning 0.

Please include the log message from crash in the bug report.

Eric,

I agree with you that the crash should be caused by that assertion.

I filed a bug, and you can see the details:

We observed similar crash when integrating cronet into our app for iOS platform.

The cronet version we forked is 90.0.4402.0. Since the crash info is limited, we have no idea to reproduce it now, but this crash is happened occasionally and continuously.

Any solutions or ideas?

Can you reopen the associated bug (https://bugs.chromium.org/p/chromium/issues/detail?id=990294) and post your stack trace and log message there?

This will help routing the issue to the correct people and making it more visible to future queries.
