We are migrating to Sun Studio 12.1 and with the new compiler [ CC: Sun C++ 5.10 SunOS_sparc 2009/06/03 ]. I am getting compilation error while compiling a code that compiled fine with earlier version of Sun Compiler [ CC: Sun WorkShop 6 update 2 C++ 5.3 2001/05/15 ].

This is the compilation error I get.

"Sample.cc": Error: Could not find a match for LoopThrough(int[2]) needed in main(). 1 Error(s) detected. * Error code 1.

CODE:

#include <iostream> 

#define PRINT_TRACE(STR) \
std::cout << __FILE__ << ":" << __LINE__ << ":" << STR << "\n";

template<size_t SZ>
void LoopThrough(const int(&Item)[SZ])
{
    PRINT_TRACE("Specialized version");
    for (size_t index = 0; index < SZ; ++index)
    {
        std::cout << Item[index] << "\n";
    }
}


/*     
    template<typename Type, size_t SZ>
    void LoopThrough(const Type(&Item)[SZ])
    {
        PRINT_TRACE("Generic version");        
    }
 */  



int main()
{
    {
       int arr[] = { 1, 2 };
       LoopThrough(arr);    
    }
}

If I uncomment the code with Generic version, the code compiles fine and the generic version is called. I don't see this problem with MSVC 2010 with extensions disabled and the same case with ideone here. The specialized version of the function is called. Now the question is, is this a bug in Sun Compiler ?

If yes, how could we file a bug report ?
