If you were on Solaris, I would say "use the libumem memory allocator", but I don't know of an equivalent for Linux. libumem is nice because it makes it very easy to track down what corrupts the stack, as it forces a core dump and exits on a bad operation, from which you can get a stack trace. You can even step through the operations if you can reproduce the problem, viewing the data and function calls using mdb (or was it dbx).
