void foo(void)
{
int i[2];
i[2] = 0;
i[3] = 0;
}
does not get warned on, even with -Wall. This might catch some subtle
bugs in gcc itself.

Compile time vs runtime warnings.
This is also a dup of bug 8268.

My vague idea would be that mudflap already does this (and *much* more). Maybe
a small part of its logic could be moved to a compile-time warning.
