Bug ID: 96142
Summary: is_constant_evaluated() returns false for variable
with constant initialization
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: barry.revzin at gmail dot com
Target Milestone: ---
Reduced from StackOverflow (https://stackoverflow.com/q/62822725/2069064), this
program:
#include <utility>
int main() {
int i = std::is_constant_evaluated();
return i;
}
with gcc returns 0. But it should return 1, this basically matches the example
we have in [expr.const]/14 with the initialization of p.
