Quoting the example here for easier reference:

int foo(int n, char buf[n]);

int main()
{
    char buf[100];
    foo(101, buf);
}


gcc with -Wall gives a warning (not an error) and clang is silent.

That makes me wonder about the state of standardization
of this situation: Could you point me to the C rule that
specifies how the above should be handled? Given that 101
is a constant, does C make the above ill-formed?
