--- Comment #13 from janus at gcc dot gnu.org ---
It should be noted that ifort (version 18.3) gives a nice runtime error for the
code in comment 0 with the proper checking flags:

$ ifort -check all -traceback c0.f90 
$ ./a.out 
forrtl: severe (408): fort: (7): Attempt to use pointer M when it is not
associated with a target

This underlines once more that the code is actually invalid (in case there was
still doubt about that).=
