            Bug ID: 102167
           Summary: Constexpr virtual destructors confuse memory leak
                    detection during constant evaluation
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: friedkeenan at protonmail dot com
  Target Milestone: ---

Minimal example:

struct S {
    virtual constexpr ~S() { }
};

consteval bool test() {
    const auto ptr = new S;
    delete ptr;

    return true;
}

static_assert(test());

Clang handles the code correctly.

Possibly related to Bug 93413, which is the reason why the virtual destructor
is not defaulted, as doing so raises the error from that report.
