[Bug 1559842] Re: SIGFPE in pthread_barrier_destroy in glibc 2.23
The pthread_barrier_init manpage specifies that count must be > 0. indeed, pthread_barrier_init() is returning EINVAL, and swrast_dri is ignoring this return value.

The line in question is: unsigned int max_in_before_reset = BARRIER_IN_THRESHOLD - BARRIER_IN_THRESHOLD % count; count is set the line before it to: unsigned int count = bar->count; (gdb) print bar->count $2 = 0 (gdb) print count $3 = 0 (gdb) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1559842 Title: SIGFPE in pthread_barrier_destroy in glibc 2.23 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1559842/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
