Ciao Fabrizio,

I have had some of this type of problem, always with the xlf compiler, but 
under Mac. Gian-Marco Rignanese identified the probable cause, after we 
arrived at the same "solution" independently:

it looks like allocating a local array with variable dimension directly in 
the variable definitions, as in

integer, intent(in) :: natom
real(dp) :: aa(natom) (as opposed to aa(3) with constant dimensions)

can give this kind of segmentation fault, at least with xlf. In any case 
it is slightly sloppy, and should be replaced by

integer, intent(in) :: natom
real(dp), allocatable :: aa(:)

allocate (aa(natom))

If you can find the routine that crashed, try this for all applicable 
arrays and see if it works. In any event we should clean the code of these 
declarations (tedious but not difficult).

In bocca al lupo

Matthieu
