Crash with low thresholds on 64bit fluka

Dear fluka experts,

I have recently installed fluka (2011.2.14 version) on a 64bit SUSE with
gfortran 4.6.1 which succesfully runs $FLUPRO/example.inp.

However, when I tried to run the attached .inp file of my own (which I
have already tested on a different machine and perfectly works) fluka
crashes as shown:
======================= Running FLUKA for cycle # 1 =======================
/usr/local/fluka/flutil/rfluka: line 358: 16788 Abandona
(core dumped) "${EXE}" < "$INPN" 2> "$LOGF" > "$LOGF"

I think the problem is related to the following cards that I used to
lower the thresholds:
* Low production threshold
* Low transport threshold
If I eliminate these cards fluka rans succesfuly on both machines.

Is there a subtle detail I was not able to notice about this cards?
Might it be a bug in the 64-bit fluka?

The following info was found at the .log file generated in the crash:

Any help will be really appreciated.
Thanks in advance.
