    Dear Fluka users and developpers,

    I'm trying to simulate a 50 MeV / 10 ľA electron beam on a U238-C2
    target, so far so good.
    The resnuclei distribution seems to be quite as I expected.
    When I calculate the radioactive decay "offline" with usersuwev program,
    I get good results, still OK.
    But, when I try the same "online" this time, using RADDECAY, IRRPROFILE,
    DCYTIMES and DCYSCORE cards, I get a core dump before the end, but not
    at the very beginning. The run goes normally till it crashes.
    I would like to know what seems to be the problem.
    I figure it's the RADDECAY option, since everything goes OK without it,
    but I don't find where.
    I don't get any understandable answer when using gdb command applied to
    the core file.
    I don't think that my machine has a memory problem or something like
    that. I run on Redhat FC3.
    Is it a problem of time left for termination (defined in START card) ? I
    tried several termination times, with the same negative result.

    Any clue ?
    Thank you.

    Sebastien
