Bug ID: 88754
Summary: Constructor call wrongly rejected
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Keywords: rejects-valid
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
Target Milestone: ---
The following valid code snippet is wrongly rejected
(since at least GCC 4.1, probably even before):
=============================================
struct A
{
A(int);
void foo();
};
template<int N> int value() { return N; }
void bar()
{
A(value<0>()).foo(); // fails
(A(value<0>())).foo(); // OK
}
=============================================
bug.cc: In function 'void bar()':
bug.cc:11:4: error: invalid declaration of '::value<0>'
11 | A(value<0>()).foo();
| ^
The code is compiled by clang and MSVC.
