Re: Firefox/Thunderbird and SSL not working with libthread_xu
:Simon "corecode" Schubert reported XXX some months ago an issue with
:Firefox/Thunderbird and SSL when using libthread_xu as the threading
:I started looking into the issue and found something that seems like a
:bug to me.
:I traced an execution of firefox with ktrace and observed something
:strange. Below is a commented extract from the 'kdump -T' output.
:// thread #4 calls umtx_sleep on 0x2a92f664
:// thread #4 never returns from this syscall, according to the kdump output
:75875:4 firefox-bin 1207996217.713757 CALL umtx_sleep(0x2a92f664,0,0)
:// thread #1 attempts to wake up thread #4
:75875:1 firefox-bin 1207996244.646643 CALL
:// I terminate the process
:75875:5 firefox-bin 1207996413.782573 PSIG SIGQUIT SIG_DFL
:The expected behaviour is for thread #4 to wake up when thread #1 calls
:I'd appreciate any feedback on the issue.
:If you need information about my environment, I'd be happy to provide it.
Could you paste all the ofktrace output between those two points? It
definitely should have woken up thread 4.
