[Gate-users] cylindrical crystal volume crash

[Eugene Gualtieri PhD]

All:

I am encountering a segmentation fault when specifying cylindrical crystal volumes, as in the CPET scanner example.
The seg fault occurs right after the "/gate/systems/CPET/crystal/attach crystal" line (see below).  Commenting it out eliminates the crash.

I am running  GATE version name: gate_v5.0.0  (1-May-2009)                     

Thanks.

Gene
