I managed to reproduce this bug in my perfectly safe and valid "helloworld" 
program by using multiple threads (pthread_create()), mutex (pthread_mutex_*()) 
and system() calls. It takes about an hour, but eventually crash the same way 
my application do, with corrupt memory and stack.

Anyone got a solution? Should I find another compatible busybox? Should I use 
another linux distribution?
