Yes you are right, they do give warnings. Thanks a lot.

Yes.  Turn on warnings and all of the compilers should give you a message;
if they don't, try reporting a bug.  ubound(x) returns an array of rank one,
and that is not allowed in standard Fortran.  Intel and Absoft clearly allow
arrays of rank and size 1 as well as scalars.
