Because each thread has it's own stack. In this case it looks like it's size
is one megabyte - that's all.

You can change size of process' stack using pthread_attr_setstacksize()
function.

pthread_attr_t attr;
pthread_attr_init(&attr);
pthread_attr_setstacksize(&attr, MY_STACK_SIZE);

pthread_create(&tid, &attr, some_fun, some_arg);

Error checking here and there and everything should be fine.
