Anna, Alberto,

It seems that there are some problems with heavy ions transport and the
last respin, even with the 64 bits gfortran 4.6.1 version.

I have tested my input files on two workstations where I installed the
fluka release (22/01/2012), and my output files (usrbin) were empty.
There is no crash and no error message.
I ran these files on my laptop with the previous version and it was OK.

It concerns heavy ions transport (Si ions at 600 MeV/u and Fe ions at 1
GeV/u) with HADROTHErapy option and nucleus-nucleus interaction on
through the ldpmqmd link. I also checked without these options.

Sincerely,
Jean-Emmanuel
