Summary: QoI: poor diagnostic for silly code
Product: clang
Version: unspecified
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
This code is silly, but GCC actually beats Clang's diagnostics by a fair margin
here:
% cat x3.cc
template <typename T, int N> struct X {};
struct S : public X<S, 1>, public X<S, 2> {
X x;
};
% ./bin/clang -fsyntax-only x3.cc
x3.cc:3:3: error: member 'X' found in multiple base classes of different types
X x;
^
x3.cc:1:37: note: member found by ambiguous name lookup
template <typename T, int N> struct X {};
^
x3.cc:1:37: note: member found by ambiguous name lookup
1 error generated.
% gcc -fsyntax-only x3.cc
x3.cc:3:3: error: reference to 'X' is ambiguous
x3.cc:1:39: error: candidates are: struct X<S, 2> X<S, 2>::X
x3.cc:1:39: error: struct X<S, 1> X<S, 1>::X
x3.cc:3:3: error: 'X' does not name a type
