1912696 - Can't unwind stacks in crashes under signature [@ __pthread_mutex_lock_full]

Status: RESOLVED DUPLICATE of bug 1807637

(Toolkit :: Crash Reporting, defect, P3)

Description

[Gabriele Svelto [:gsvelto]]

Crash report: https://crash-stats.mozilla.org/report/index/f9fa7a91-e6a2-4404-92ed-383530240811

Reason: SIGSEGV / SEGV_ACCERR

Top 1 frame:

0  libc.so.6  __pthread_mutex_lock_full  /usr/src/debug/glibc-2.40/nptl/pthread_mutex_lock.c:194

We only ever get one frame, it's odd. Either there's a bug in dump_syms / rust-minidump or the debug information is buggy, or maybe there's some new stuff we don't support.

The bug is linked to a topcrash signature, which matches the following criteria:

• Top 20 desktop browser crashes on beta (startup)
• Top 5 desktop browser crashes on Linux on beta (startup)

:gsvelto, could you consider increasing the severity of this top-crash bug?

This bug only affects users with Nvidia closed-source drivers from the 560.x version line. Not bumping the priority because we're unlikely to be able to do anything about it.

Comment 4

[BugBot [:suhaib / :marco/ :calixte]]

Based on the topcrash criteria, the crash signature linked to this bug is not a topcrash signature anymore.

This bug only affects users with Nvidia closed-source drivers from the 560.x version line. Not bumping the priority because we're unlikely to be able to do anything about it.

Also 570.x versions:

• bp-b621ca1e-6d88-4bac-83a5-75f970250315
• bp-fb0705b6-cc30-4226-a285-083b70250314

But I think some or most of the Thunderbird crashes are not driver related. Many comments mention logging in or just exiting Thunderbird.
