Bug ID: 97279
Summary: GCC ignores the operation definition of the template
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: tangyixuan at mail dot dlut.edu.cn

Hi, gcc selects the overloaded definition operation+() although it is not
declared before.
$ cat s.cpp
#include <iostream>
struct S {
template <typename T>
void operator+(T) { std::cout << "1" <<"\n"; }
};
namespace N {
template <typename T>
void func(const T value1) { S s; s +(value1); }
}
struct S1 {};
namespace N {
void operator+(S&, S1) { std::cout << "2" <<"\n"; }
}
int main(int, char**)
{
S1 s1;
N::func(s1);
}
$ g++ s.cpp
$ ./a.out
2
$ clang++ s.cpp
$ ./a.out
1

Hmm, ICC also produces 2. Not quite sure what's going on here.

ICC produces 2 by default, but produces 1 when the -strict-ansi command line
option is used.
