I think your program has undefined behavior:

int main(int argc, char *argv[])
{
	int c = 'z';
	c = getc(stdin);

	if (c == EOF)
		printf("EOF!\n");
	else
		printf("got '%c' (0x%x)\n", c, c);

	return 0;
}

The first c should probably use %d, not %c, since c is an int. Maybe something like:

printf("got '%d' (0x%x)\n", c, c);

Use g++ -Wall or a Sanitizer to vet the code at compile time.
