It took us a while (3+ months!) to get around to trying out the FORTRAN
compiler on our Crimson/VGX [too many other neat things to play with ;-) ],
but upon doing so we discovered that f77 (actually ugen) core dumps on even
the most trivial code:
	program test
	write(*,*) '!11-PDP eht edisni deppart m''I !pleH'
	stop
	end

The error message is usually:
	Fatal error in: /usr/lib/ugen  Signal 10 - core dumped

although on occasion I've gotten a SIG 11 while playing with compiler options.
I called the TAC (call #151880) but was regretfully informed that the 
warranty on our Crimson had expired (paperwork for a maintenance agreement
is lost somewhere in the NASA bureaucracy).  I'm sure something is just
incorrectly installed.  We are running Irix 4.0.5_, with 3.4.1 ftn.* and
the 3.4.4 maint_ftn.* images. I have re-installed the maint updates, but
not the entire Fortran package.
Any clues or quick fixes?  Or should I just re-install everything?  Or is it
something else seemingly unrelated?
TIA!
