Bug ID: 81506
Summary: Invalid declaration with decltype accepted
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Keywords: accepts-invalid
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
CC: paolo.carlini at oracle dot com
Depends on: 51786
Target Milestone: ---
The error message "declaration does not declare anything" is not
triggered in certain cases when using decltype:
===================================
template<int> struct A
{
A() { decltype(this); }
};
A<0> a;
===================================
It *is* triggered if I make A a non-template class.
This is actually the second testcase from PR51786. While the first one
was successfully fixed, the second testcase still doesn't work.
Btw, clang produces a warning for this case.
