[Weechat-dev] Race Condition Crashes on 0.4.2 and 0.4.3

[Jason A. Donenfeld]

Hi all,

I've been receiving crashes with weechat since 0.4.2. I had hoped
0.4.3 would fix things, but it does not. The latest version I can run
is 0.4.1.

When weechat starts, it segfaults and prints this message:

 weechat: ../nptl/pthread_mutex_lock.c:350: __pthread_mutex_lock_full:
Assertion `(-(e)) != 3 || !robust' failed.

                                                     Aborted
or

weechat: tpp.c:62: __pthread_tpp_change_priority: Assertion `new_prio
== -1 || (new_prio >= __sched_fifo_min_prio && new_prio <=
__sched_fifo_max_prio)' failed.


                               Aborted

Othertimes it exits with "illegal instruction" and this in dmesg
"[558232.781319] traps: weechat[25733] trap invalid opcode
ip:6a2866c6aad4 sp:7173723bd320 error:0 in
libpthread-2.18.so[6a2866c58000+19000]", and othertimes with simply
"Aborted".

I suppose there's some sort of race I'm hitting.

This occurs on Gentoo Hardened.

Thanks,
Jason
