Description

Email from Edward:

I don't understand where is this seg fault in SciFiPlaneTest coming from.

In my laptop, I have the rest included, I do scons -c; scons; ./run_tests and everything is fine; in jenkins there's always a seg fault.

Reply from Rogers:

The place I have run into trouble between desktop and server is that the
test scripts are generally in a random order. So if you allocate or free
some memory in one test, you can accidentally use that - or not - in
another test. Particularly bad with geant4 because geant4 can't clear
it's memory allocation (i.e. it has nasty globals that never get freed).
So you can find that you allocated a nasty G4 global in one test, and
then try to do something in another test and it works or not depending
on the unit test order.

Basically Geant4 sloppiness...
