Bug ID: 66990
Summary: Wrong diagnostics when template being specialized is
ambiguous
Product: gcc
Version: 5.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: rs2740 at gmail dot com
Target Milestone: ---
Consider:
namespace A {
inline namespace B { template<class> struct C; }
template<class> struct C;
template<> struct C<int>{};
}
Lookup for `C` is ambiguous, obviously, but the diagnostics doesn't say that.
Instead, we get (with gcc
prog.cc:4:23: error: 'C' is not a class template
template<> struct C<int>{};
^
prog.cc:4:28: error: template specifiers not specified in declaration of
'template<class> struct A::C'
template<> struct C<int>{};
^
which is rather unhelpful.
