Cannot access memory at address

[Andrew Arro]

Hi! I have a trauble which seems to be stack trauble - but i am not
sure...

Why i think this is stack? because 

where

in the gdb shows no stack trace and only says

Cannot access memory at address

the code runs about 100 pthreads, uses select and socket IO.


So, my pthreaded code crashes by Segmentation Fault in RANDOM
functions calls - and GDB shows smth like this:


Testes on 2 differerent 2.4.* LINUX boxes, one with gcc 3.0.4 + gdb
5.1.1 and another gcc 2.96 + gdb 5

I think my main question is how can i debug this, any hints?
