I recently tried version 13.1 and found the nice result that
my attempts at using coarrays
www.fortran.com/13_heat4.f90 for example

Also got the strange result following (Yeah, -v is not
legal, but I usually don't get a compiler error on legal code :-).
Running W7-64 on a 2-core i3 laptop.
$ ifort -v
