Bug ID: 102090
Summary: Placement-new is not constexpr
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: friedkeenan at protonmail dot com
Target Milestone: ---
When calling placement-new in a constant expression, a compiler error occurs
saying that `void* operator new(std::size_t, void*)` is not constexpr; see
https://godbolt.org/z/8enoG9G57 for a minimal example.
As far as I can tell, the fix should just be adding constexpr to the signature.
