Description dbailey 2001-04-13 10:46:16 CEST

If I fire hadrons above a TeV or so into high Z materials I occasionally get
segmentation faults after some number of events. e.g. 5 TeV hadrons into tungsten
inevitably produce segmentation faults after a thousand events or so, and less
frequently at energies down to a TeV. The offending events all seem to be trying
to produce more than 512 secondaries.

   Increasing MAXPART in G4HEInelastic from 512 to 1024 seems to solve the
problem (or at least postpones it).

   I am basically using the Example N04 physics list.

Fix is underway. Please use the
'SetMaxNumberOfSecondaries(int )' method of the high_energy models
to increase the allocation for a temporary workaround.

Many greetings,

Hans-Peter.

Dear Harm,

  can you please take care?

Many greetings,
