Problem 1122

In our simulation we have the cases when only light ions (A<10) are requested. In such cases we have the segmentation fault (full diagnostics attached below). We expect that several checks should be added to the lines like #8 [G4LossTableBuilder.cc#line 84 :  size_t n_vectors = (list[0])->length();]
in order to fix such crashes. In our case list[0]==0. 

We use geant4.9.2.p02, geant4_vmc 2.7b, and FairRoot.


 *** Break *** segmentation violation

The lines below might hint at the cause of the crash.
If they do not help you then please submit a bug report at
http://root.cern.ch/bugs. Please post the ENTIRE stack trace
from above as an attachment in addition to anything else
that might help us fixing this issue.
