Bug ID: 113110
Summary: GCC rejects call to more specialized const char array
version with string literal
Product: gcc
Version: 13.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jlame646 at gmail dot com
Target Milestone: ---
GCC seems to rejects valid code. The following code is rejected by gcc and
clang while accepted by msvc. As the first version is more specialized for
const char arrays, it seems the first version should be used.

```
#include <cstring>
using namespace std;
// fist version
template <size_t N, size_t M>
int compare(const char (&a)[N], const char (&b)[M]) {
return strcmp(a, b);
}
// second version
template <typename T>
int compare(const T &a, const T &b) {
if (a < b) return -1;
if (b < a) return 1;
return 0;
}
int main() {
compare("dog", "cat"); //gcc and clang rejects while msvc accepts
}
```
