Making the C stack large enough is not solving it on 32 bit architectures with enough physical RAM that you can't/don't want to waste address space. And on 64 bit architectures address space isn't a problem, but the memory from a temporary large stack can't be re-used without swapping the old stack contents out which is slow.
