>Description:
Member template functions overloading fails when overloading is
based on the template parameter list. It fails with g++-3.1 older than
pre-2 version, and g++-3.2. It works outside any class.
Referring to sections (14.5.5.1-4) and (14.5.2-8) it seems to be
a bug. g++ < 3.1 accepts it, como and icc too.
>How-To-Repeat:
struct foo
{
template<class T>
void bar();
template<int I>
void bar();
};
$ g++-3.2 template_overloading.cc
template_overloading.cc:7: `template<int I> void foo::bar()' and `
template<class T> void foo::bar()' cannot be overloaded
>Fix:
Use namespace instead of struct, but not always possible.
