Bug ID: 110584
Summary: Constant is not visible in nested lambda
Product: gcc
Version: 13.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: fchelnokov at gmail dot com
Target Milestone: ---
This program (created by my colleague Artur)
void foo(float);
int main() {
constexpr float x = 0;
(void)[&] () {
foo(x);
(void)[] () {
foo(x);
};
};
}
is accepted in Clang and MSVC, but GCC complains:
error: 'x' is not captured
note: the lambda has no capture-default
'const float& x' declared here
5 | foo(x);
