Possible bug in g++ - template specialization

[Maciej Cencora]

Hi,

I think I've found a bug in g++. Let's say we have following files:

// a.hpp

template<typename T>
void func1()
{
        // general code
}

// a.cpp

#include "a.hpp"

template<>
void func1<int>()
{
        // specialized code
}

// main.cpp

#include "a.hpp"

int main(void)
{
        func1<int>();
        
        return 0;
}


Now when we run the program compiled with: g++ main.cpp a.cpp -o main
specialized version of func1 will be called, but when compiled with
-Os flag the general version will be called.
I'm not an expert but I believe the -Os behaviour is the correct one.

Please CC me when replying, as I'm not subscribed to the mailing list.
