Yes, indeed. This goes back to gcc-4.3 at least.

I wonder if it is sufficient to test if there are any host associated
variables?
I have my thinking cap on:
(i) Is this standard violating? I guess so, since the result is aliasing the
host associated symbol 'a'.
(ii) Is this only an issue for host association?
(iii) Is it sufficient to check if the lhs is host associated into the function
call?
Many thanks for flagging this up to us. It's really nice to know that the
leader of the Absoft fortran team is helping us out :-)
Cheers
