Bug ID: 24242
Summary: Misleading diagnostics when template being specialized
is ambiguous
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Consider:
namespace A {
inline namespace B { template<class> struct C; }
template<class> struct C;
template<> struct C<int>{};
}
Name lookup for `C` is obviously ambiguous, but the resulting error message
doesn't mention that at all:
prog.cc:4:23: error: explicit specialization of non-template struct 'C'
template<> struct C<int>{};
^~~~~~
prog.cc:4:23: error: redefinition of 'C' as different kind of symbol
prog.cc:3:28: note: previous definition is here
template<class> struct C;
^
2 errors generated.
