Comment 8 for bug 840641

Thanks for the replay,
The latest update didn't help, so I try to do some debugging.

glibc-common-2.14.90-12.999.i686
glibc-debuginfo-2.14.90-12.999.i686
glibc-2.14.90-12.999.i686
glibc-debuginfo-common-2.14.90-12.999.i686

I'm not strong with gdb... Especially we have python code here, So here are my steps, please help me if I'm doing wrong:

I found a lot of information about printing stack etc., please let me know what information you want and the best way to get it

Thank you
