Bug ID: 62145
Summary: match rulers in overload functions
Product: gcc
Version: 4.9.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: pangbw at gmail dot com
For this small program, G++ and clang++ don't agree with each other:
1. cat x2.c
#include <stdio.h>
char f(...) { return '\1'; };
int f(void*) { return 999; }
constexpr int t2(int n) { return sizeof f(n*0); }
int main()
{
char b[ t2(0) ];
printf("sizeof b is %d\n", sizeof(b));
return 0;
}
2.
$ g++ -std=c++0x x2.cpp
$ ./a.out
sizeof b is 4
$ clang++ -std=c++11 x2.cpp
$ ./a.out
sizeof b is 1
It shows G++ is calling f(void*), but clang++ is calling f(...). which one is
right?
