A newly allocated object (or array or pointer) with default initialization is
now tested with the ALLOCATED() or ASSOCIATED() before initialization is done.

Confirmed from 4.8 up to trunk (6.0). Duplicate of pr59796?

pr59796 is a different issue (a deallocate on dangling pointers), which I don't
think is standard conforming. This PR is for standard conforming code, and will
only fail in the presence of default initialization.
