Hi,

I'm experiencing a segmentation fault/core dump at the end of my program
after the deletion of the RunManagerKernel when using the
G4PAIPhotModel. The segmentation fault is reproducable with TestEm8 and
the testPAI.mac macro when using the option

/testem/phys/addPhysics pai_photon

The error occurs with Geant4 version 10.0.p02 and 10.1.beta01.

I'm working on lxplus using csh with the following options:

if ( -r /afs/cern.ch/sw/lcg/contrib/gcc/4.8.0/x86_64-slc6-gcc48-opt/setup.csh ) then
   source /afs/cern.ch/sw/lcg/contrib/gcc/4.8.0/x86_64-slc6-gcc48-opt/setup.csh
endif
if ( -r /afs/cern.ch/sw/lcg/external/geant4/10.0.p02/x86_64-slc6-gcc47-opt/bin/geant4.csh ) then
   source /afs/cern.ch/sw/lcg/external/geant4/10.0.p02/x86_64-slc6-gcc47-opt/bin/geant4.csh /afs/cern.ch/sw/lcg/external/geant4/10.0.p02/x86_64-slc6-gcc47-opt/bin
endif

The relevant valgrind output is here:

[snip]

UImanager deleted.

StateManager deleted.

RunManagerKernel is deleted. Good bye :)

Following in the valgrind output are "Invalid write" and "Invalid free()
/ delete / delete[] / realloc()" at the same location.
