Bug ID: 103048
Summary: Mandatory copy elision used for catch-by-value
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: songyuanyao at qq dot com
Target Milestone: ---
struct B {
B() = default;
B(const B&) = delete;
};
int main() {
try {
throw B{};
}
catch (B) {}
}
This code shouldn't compile according to [except.throw]/5:
---
When the thrown object is a class object, the constructor selected for the
copy-initialization as well as the constructor selected for a
copy-initialization considering the thrown object as an lvalue shall be
non-deleted and accessible, even if the copy/move operation is elided
([class.copy.elision]).
