> Current gcc ICEs again on CP2K

I tried to reproduce this with gfortran (trunk) of yesterday with CP2k of today
- and I failed to get an ICE. I tried then to directly use gfortran-4.2 (also
yesterday's version) without any ICE. I also tried gfortran 4.3 20070102.

> gfortran -c -O3 -ftree-vectorize -ffast-math -march=opteron -fopenmp
> mc_coordinates.f90
> mc_coordinates.f90: In function ?check_for_overlap?:

This is in my CP2k:
         box_length(1:3)=abc(1:3)
where
  REAL(KIND=dp), DIMENSION(1:3) :: abc, box_length

Can you try to find the minimal set of options which causes this bug?
e.g. -O0 no -ftree-vectorize -ffast-math, no -fopenmp etc.
What is your exact version of gfortran?

By the way, I think one should leave in future this PR closed and open new PR;
this PR is a wild mixure between a meta bug (5 dependend bugs, now fixed) and a
couple of rather independent bugs reported directly here.
