How can I check stack is OK ?

Hello,

I'm developing a C++ application that runs under vanilla 2.6.27.35 with busybox 1.14.1

The application is one process divided into 8 threads.

The stack allocated for a thread is 256KB

What tool can I use to make sure that my stack is big enough ?

I suspect that in a specific scenario the stack overflows.

Thanks,
Zvika

probably you can try valgrind: http://valgrind.org/

Compile your program with -fstack-check. GCC will add some stack protection code. Valgrind is a good tool too. Using the two you should be able to detect most of the problems.
