Problem 1100

I would like to report an issue with Qt UI with Geant4 9.3 and Qt4 on SLC5 with gcc4.1
When G4 is compiled with Floating Point Exception on: 
export G4DEBUG=1
export G4FPE_DEBUG=1

any application crashes (i.e. exampleN07) at startup when trying to create the Qt UI widgets.

I attach at the end of this mail the stack trace.
As you can see it seems that the problem is Qt related, so I am not sure it's a real issue for G4, also please note that this crash happens ONLY when G4 is compiled with FPE support, no problems if this option is turned off.
I can only add that I have the following warnings when compiling G4 (but I do not know if this is related to the problem):

Thank you,
Andrea
