Dear all,

after a successful simulation test, we have tried digitization. We have used "case 17" for the emc geometry and we get segmentation fault when we have particles in the forward direction. We think it is a problem related to the mapper of the forward endcap or shashlyk. We used BoxGenerator and shoot photons in different directions. When we shoot in the backward region(no hits in forward endcap or shashlyk calorimeter) there is no error. When we shoot in the forward region we get the error.

Could anybody take a look to test, and eventually fix, the mapper used by the latest emc geometry?

Thank you very much.


ps. this is an example of the message we get in the log file when problems are found:
