#include <cstdio>
int main()
{
printf("%s\n", (char*)0); // run-time error for g++ 4.3.2,
} // while ok for g++ 3.4.4
run-time error:
10 [main] a 1808 _cygtls::handle_exceptions: Error while dumping state
(probably corrupted stack) Segmentation fault (core dumped)
expexted behavior:print nothing or (null)
workaround: use cout
comment:
Many people still prefer printf to cout. The disabled function make
printf almost useless.
