[Bug c++/20295] New: template fails to match empty array

[igodard at pacbell dot net]

In:
template<typename T, int n>
void    thru(T (&arr)[n]) {}

int a0[] = {};
int a1[] = {0};

int main() {
    thru(a1);
    thru(a0);
    }

you get:
~/ootbc/members/src$ g++ foo.cc
foo.cc: In function `int main()':
foo.cc:9: error: no matching function for call to `thru(int[0u])'

I think zero is still an int, at least the last time I heard :-)
