	I believe this particular case was false positive.
	Before committing workarounds, the code was like this.
	There's no possibiltiy for the code to visit call to baz()
	when family is not AF_INET nor AF_INET6.

	If we initialize pointer p to NULL on declaration,
	it may shut up the compiler but hides other potential trouble.

int func()
{
	char *p;

	switch (family) {
	case AF_INET:
	case AF_INET6:
		break;
	default:
		return -1;
	}

	...
	switch (family) {
	case AF_INET:
		p = foo();
		break;
	case AF_INET6:
		p = baa();
		break;
	}

	baz(p);		/*pmax compiler got angry on it with uninitialized p*/
}
