Dear Joshua,

since the reported crash looks very rare, we need your collaboration to
reproduce it. Thanks for sending us the input file, possible ancillary
files (user routines and - if any - respective input data files), and
especially the relevant random seed file (the one you find in the
temporary directory of the crashed run, i.e. fluka_###/ran*). Which
version do you use: g77 or gfortran?
I tend not to believe that this is symptomatic of a bigger problem, but
certainly deserves to be fixed.

Kind regards

Francesco

I can’t seem to find PHNCEV discussed anywhere, nor this error message. Does anyone know what causes this? It is obviously very rare, but I’d like to understand it, so I know it isn’t symptomatic of a bigger problem.
