@ldionne thanks for the workaround! However, it doesn't help even with the original reproducer in godbolt (https://gcc.godbolt.org/z/be7xMhcn3). We've done some progress cleaning up non-conforming iterators (mostly adding `const` to dereference and comparison operators), but I'd still find it useful to have a working workaround for this in case we're stuck with some of the fixes. I guess, other libc++ users would also appreciate a more controllable way to enable enforcement of iterator requirements.
