I do recall running into some sort of problems w.r.t. standards conformance
with this type of intrinsic in array specifications in the past (the details
allude me), so I'm not certain this is legal.  However, with a similar code
(without the loop that seems to be causing the problem) I can't get gfortran to
produce an error or warning with any combination of -std and -pedantic, and
size(N) returns the expected value.  So if it's not legal code, there's another
bug to go with the ICE!

(*sigh* Another problem of not having standards documents readily available
without forking out cash...  or is there a reliable Fortran specification
living on the web somewhere?)
