Hi, Bradley.

I am able now to process the majority of the beam-tri StdHep events but occassionally I'm seeing a Segmentation fault (not in every file though and it seems pretty rare).

When I skipped to the specific events with the error and did a gdb backtrace I see this for one of them:

0x00007ffff0575e7e in UTIL::lStdHep::Event::read (this=0x45499d8, ls=...) at /work/ilcsoft/slic/HEAD/lcio/HEAD/src/cpp/src/UTIL/lStdHep.cc:420
420        if (*version == '2') {

This is a crash in an LCIO utility class for reading StdHep files, so it is not technically in the SLIC code.

I'm not quite sure of the exact cause, because reading of the version is done for every event.

Is it possible that every so often the event generator code is not assigning a version correctly or possibly the entire event is corrupted?

I'll continue to investigate and let you know what I find out here.
