Hmm,
19:42 <thiago> in fact, it looks like libpthread itself (set_thread_area, 
set_tid_address)
19:42 <djurban> the process tries to change the block size, but brk(0x80b9000) 
didnt return 0  -> error, the process didnt check the result of
                brk(0x80b9000) and tried to write to the memmory which caused 
a sig11
19:43 <djurban> I thouh it was an error in glibc
19:43 <djurban> ie in nptl
19:43 <thiago> that looks like nptl itself
19:44 <thiago> it's setting the thread pointer, then it's setting one signal 
(SIG32)
19:44 <thiago> it sets the stack to 8MB, does a futex
19:45 <djurban> but my friend thhinks its qt's fault, because brk returns what 
it should and qt doesnt check the returned values
19:45 <djurban> Im in the middle of searching for the code that does it
19:45 <thiago> RETURN VALUE
19:45 <thiago>        On  success,  brk returns zero, and sbrk returns a 
pointer to the start
19:45 <thiago>        of the new area.  On error, -1 is returned, and errno is 
set to ENOMEM.
19:45 <thiago> can you valgrind that?
19:46 <djurban> unfortunately nptl doesnt allow valgrinding
BTW. Moglbys sie w miare szybko (20 minut pojawic na ircu?)
