What hardware?

If the synthetic target and you are running a very recent Linux
kernel, that kernel may have problems with the brk() system call used
to initialize the eCos heap. I implemented a workaround last weekend
and checked it into anoncvs.

Otherwise it may be random memory corruption somewhere in your
application, or a stack overflow or similar. First try to run some of
the standard networking tests from net/common and see if they work.
