Crash witth ppsource proton-heavy nuclei

Dear FLUKA team,

I found a crash running FLUKA with proton-heavy nuclei (i.e. beam-beam)
using specsour with sdum=ppsource. The error message is:

mazziot_at_gridba14>$FLUPRO/flutil/rfluka -e emissflukadpm -N0 -M1 pX_dpm
$TARGET_MACHINE = Linux
$FLUPRO = /lustre/home/mazziot/Fluka/fluka2011.2.14

Attached are the input and the geometry files. I am using user files
mgdraw.f source.f usrein.f usreou.f usrini.f usrout.f to write the
output data (taken from the example
http://www.fluka.org/fluka.php?id=examples&sub=example1) and DPMJET
option (i.e. using $FLUPRO/flutil/ldpmqmd -m fluka -C usrini.o usrout.o
mgdraw.o usrein.o usreou.o -o emissflukadpm). Indeed I also found the
same crash running without the DPMJET option.

It works fine with proton-proton beam and it seems that removing the line
PHYSICS 1.D+06 1.D+06 1.D+06 1.D+06 1.D+06 1.D+06PEATHRES
it works fine for heavy nuclei too.

Thank you in advance.

Best regards,
Nicola
