Bug ID: 123296
Summary: Can't direct-list-initialize unnamed temporary int&
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: blubban at gmail dot com
Target Milestone: ---
(apologies if this is wrong terminology, I think this is case 2 of
https://en.cppreference.com/w/cpp/language/list_initialization.html )
int main() {
int num;
using intref = int&;
int& ref = intref{ num };
}
No flags needed.
Expected: Compile it. Maybe with an unused-variable warning.
Actual:
<source>: In function 'int main()':
<source>:4:28: error: cannot bind non-const lvalue reference of type 'intref'
{aka 'int&'} to an rvalue of type 'int'
4 | int& ref = intref{ num };

Compiler returned: 1
