[Users] Compilation error with ifort

[Roland Haas]

Hello Lorenzo,

the heavy Fortran code in PITTNull has been giving ifort trouble every
once in a while. Basically it tries to optimize very hard and sometimes
just fails and gives up (or encounters various errors). Sometimes it
may also use too much memory. It is not clear from the error message
part you included what it would be.

The option list looks ok to me.

Please take a look at the "general guidelines for questionss" in
http://einsteintoolkit.org/support.html

If I were in your shoes I would try these two things:

* compile with -O1 (if that works one can restrict it to just that one
  file see eg what is done in
  repos/mclachlan/ML_ADMConstraints/src/make.code.deps but using -O1
  instead of -fp-model precise)

* compile with -j1 (which might help memory consumption if it is a
  per-user memory limit and not per process)

The full make.log would be helpful.

Yours,
Roland
