Well, obviously.  Also obviously in the code in which I discovered the bug the
dimensioning variable was set.

Attached are revised codes that are 100% legal, give no warnings or errors with
either g95 or ifort, pass Lahey's online standards conformance test and still
produce the ICE with gfortran 4.2.

Interestingly, if i is defined in nnh.f90 before the call to f the ICE goes
away.

Thus, while it may not effect the WONTFIX, I'm changing the keyword to
ice-on-valid-code.

(OK, that's the end of my "I know Fortran!" rant! ;-)
