Description cf 2001-08-17 07:40:41 CEST

Running a simulation of gamma-rays i get a crash with this message:

G4VProcess::SubtractNumberOfInteractionLengthLeft()  negative
currentInteractionLength

*** G4Exception: Aborting execution ***
Abort

I am using lots of processes (EM, ion, Hadronics). I dont know which process
caused this - i tried using /process/verbose 2 but that doenst seem to give more
info, even thought the G4VProcess.hh file seemed to suggest it might. Is there
anything i can do to get around this?

Hi,
 To get the information, the source code must be compiled with G4VERBOSE option.
 Also, please try "/tracking/verbose 2" for getting information from tracking,
which can be achieved without the above mentioned compilation option.
