Bug#557158: libc6

[Mateusz Jasiński <matt1606@gmail.com>]

Hi,

I'm using libc6 version 2.10.2-2 in up to date debian sid. I'm observing some 
SEGFAULTS while running a threaded program. I'm writing a computer simulation 
program using custom build of itpp library and pthreads. My program is 
crashing randomly during execution (maybe due to the race condition - it fits 
to my observations). The problem also occurs on some random apps, for example 
from my desktop env. (KDE4.3.4). It's the same error but in different libraries 
(itpp, qt, kdelibs...). The only report I'm getting is in dmesg.log which is:

alg_pt[8688]: segfault at 8056000 ip b7594220 sp a65c4d60 error 4
alg_pt[8687]: segfault at 8056000 ip b7594220 sp b66c5d60 error 4 in 
libitpp.so.6.0.6[b73ff000+335000] in libitpp.so.6.0.6[b73ff000+335000]

I was trying to debug my code using gdb, and to my surprise it was running 
correctly, no segfaults during execution. I've also setup an lenny chroot env. 
and recompiled the itpp libs. What I can confirm that the problem doesn't occur 
in lenny,
