Subject: Account creation on GCC bug tracker (or issue report)
Date: Mon, 12 Jun 2017 08:44:00 -0000 [thread overview]
Message-ID: <CAHwPpv6Y+Gm6YvYo2iUeVMQJA7_k52vRvY2-yMMe25pTrrkLoQ@mail.gmail.com> (raw)
Hi,
I'm not able to create an account on the GCC bug tracker.
I'd like to report a bug with G++7.1 that does not accept this code anymore:
template <int line, typename FuncSig, FuncSig f>
struct HelperWrapper;
// [...]
template <int line, typename Ret, Ret (&Func)()>
struct HelperWrapper<line, Ret (&)(), Func>
{
static inline int WrapFuncT(const int)
{
return 0; // Changed
}
};
// Unary
template <int line, typename Ret, typename Arg1, Ret (&Func)(Arg1)>
struct HelperWrapper<line, Ret (&)(Arg1), Func>
{
static inline int WrapFuncT(const int)
{
return 1; // Changed
}
};
// Binary
template <int line, typename Ret, typename Arg1, typename Arg2, Ret
(&Func)(Arg1, Arg2)>
struct HelperWrapper<line, Ret (&)(Arg1, Arg2), Func>
{
static inline int WrapFuncT(const int)
{
return 2; // Changed
}
};
Rejected with error:
a.hpp:683:16: error: partial specialization 'struct
Type::Implementation::HelperWrapper<line, Ret (&)(), Func>' is not
more specialized than [-fpermissive]
struct HelperWrapper<line, Ret (&)(void), Func>

FuncSig, FuncSig f> struct Type::Implementation::HelperWrapper'
struct HelperWrapper;

struct HelperWrapper;
^~~~~~~~~~~~~
a.hpp:707:16: error: partial specialization 'struct
Type::Implementation::HelperWrapper<line, Ret (&)(Arg1, Arg2), Func>'

struct HelperWrapper<line, Ret (&)(Arg1, Arg2), Func>
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
a.hpp:640:16: note: primary template 'template<int line, class
FuncSig, FuncSig f> struct Type::Implementation::HelperWrapper'
struct HelperWrapper;
While previous version used to accept this fine, and all other C++
compiler are ok with it
I've created a godbolt.org/g/uW3D7O example where you can test all
other compilers.
What is the right way to report a bug ?
Best regards,
Cyril RUSSO
