I got some more insight using:
int checkstack(int depth)
{
if (depth <= 0)
return 0;
checkstack(depth - 1);
}
int recurse(int depth)
{
char stack[2048];
char *heap;
memset(stack, depth % 256, sizeof(stack));
heap = (char*) malloc(2048);
/* Call recursively */
printf("stack %p heap %p depth %d\n", stack, heap, depth);
checkstack(depth);
recurse(depth + 1);
return 0;
}
main()
{
recurse(0);
}
This print lines like these:
stack 0xbed4b118 heap 0x92a1cb8 depth 9356
... or in other words over 3GB of space between the stack and
the heap. No wonder I'm not seeing any core dumps.
