Right question is "is this guaranteed to work by spec?".

Spec is silent about this but in practice this should work. Real
question is here why would you want "pointer to class" when you have
normal reference and what such "pointer" would give you.

Since class is a reference it's a pointer value (address anyhow).
Hence you'll get an address of value holding that address (e.g. of a temporary) then dereference it as void** pointer.

It's sometimes useful in this particular case to circumvent type-system in order to do smth (interface with C etc.).
