Bug ID: 47316
Summary: 'error: parameter declarator cannot be qualified' on
seemingly valid code
Product: clang
Version: 10.0
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++14
Assignee: unassignedclangb...@nondot.org
Reporter: sly...@inbox.ru
CC: blitzrak...@gmail.com, erik.pilking...@gmail.com,
llvm-bugs@lists.llvm.org, richard-l...@metafoo.co.uk
Original bug is observed on https://bugs.gentoo.org/739036 where
source-highlight was buildable by g++-10 and failed b clang++-10.
Reduced example:
namespace a {
enum c { d };
class e {
public:
e(c);
};
}; // namespace a
a::e f(a::e(a::d));
gcc succeeds to build the example, clang fails:
$ g++-10.2.0 -std=c++14 -c -o test_exception_main.o bug.cpp && echo OK || echo
FAIL
OK
$ clang++-10 -std=c++14 -c -o test_exception_main.o bug.cpp && echo OK || echo
FAIL
bug.cpp:10:16: error: parameter declarator cannot be qualified
a::e f(a::e(a::d));
~~~^
1 error generated.
FAIL
gcc bug, clang bug or known ambiguity? Looks like clang does not see a::d as an
enum value.
