I've been contacting the maintainers of some software (ccp4) that I
have packaged for fink, and I got this rather disturbing reply this
morning. It sounds like gfortran on intel is problematic. Has
anyone else had experiences, good or bad, with gfortran on intel? I
was actually about to buy one but this put me off.
Hi Bill
I have not been down the fort77 line yet. The results from gcc
4.1.0 on a linux box are not encouraging; we get the os x failures
plus a few more.
Still, this is better than gfortran on an intel Mac. Every code
that uses a maths function fails at runtime with an EXC_ARITHMETIC,
including the gcc testsuite math.f90 . gcc/g++ seem to work nicely
though.

Hi Charles:
Thanks for confirming. I did get sfcheck to pass the tests when I
recompiled using gfortran -0O. No such luck with the other two.
If the bulk problem is minor, then there is only one problem: oasis.
As a temporary workaround, would it be possible to use fort77 (or
f2c) to compile it, or would that require recompiling all the
libraries to which it links?
g77-3.4.3 works great, but apparently won't be available on intel
macs.
All the best,
Bill

Dear All,
I can confirm Bill's observations. gfortran 4.1 seems to be a
step back from the pre-release, at least on os x.
bulk.exam : the example fails, but the programs are running
correctly. The tee does not seem to be picking up the fortran >>
output.
oasis_sir/oas.exam : end of file. Looks like a failure to
rewind a file.
sfcheck.exam : unknown reason.
Francois is checking how 4.1 performs under linux.
Given this, if you have the option of using g77, this would be
the way to go.
