Re: errors/seg-fault in hdgeant

[Beni Zihlmann <zihlmann@jlab.org>]

Hi Mark,
I used your control.in file runing hdgeant in debug mode but using the 
latest
repository code. I do not see the geometry errors, however, I also get a 
segmentation
fault as indicated below. It seems the segmentation fault happens in a 
geant routine.
maybe the data it gets is corrupted according to the geant manual:*
**CALL GMICAP * GMICAP 
<http://www.kph.uni-mainz.de/computing/docu/geant/Geant-HTML/node352.html#GMICAP> 
calls the MICAP routines to handle the low-energy
interaction of neutrons. It writes the eventual secondaries to the GEANT 
stack. GMICAP 
<http://www.kph.uni-mainz.de/computing/docu/geant/Geant-HTML/node352.html#GMICAP> 

is called from GFMFIN 
<http://www.kph.uni-mainz.de/computing/docu/geant/Geant-HTML/node352.html#GFMFIN>. 


Program received signal SIGSEGV, Segmentation fault.
