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): src/G4OpenGLQtViewer.cc: In member function ‘void G4OpenGLQtViewer::moveScene(float, float, float, bool)’: src/G4OpenGLQtViewer.cc:1530: warning: passing ‘G4double’ for argument 1 to ‘void G4OpenGLQtViewer::moveX(int)’ src/G4OpenGLQtViewer.cc:1531: warning: passing ‘G4double’ for argument 1 to ‘void G4OpenGLQtViewer::moveY(int)’ src/G4OpenGLQtViewer.cc:1532: warning: passing ‘G4double’ for argument 1 to ‘void G4OpenGLQtViewer::moveZ(int)’ src/G4OpenGLQtViewer.cc: In member function ‘void G4OpenGLQtViewer::rotateQtScene(float, float)’: src/G4OpenGLQtViewer.cc:1555: warning: passing ‘float’ for argument 1 to ‘void G4OpenGLQtViewer::rotateTheta(int)’ src/G4OpenGLQtViewer.cc:1559: warning: passing ‘float’ for argument 1 to ‘void G4OpenGLQtViewer::rotatePhi(int)’ src/G4OpenGLQtViewer.cc: In member function ‘void G4OpenGLQtViewer::rotateQtCamera(float, float)’: src/G4OpenGLQtViewer.cc:1578: warning: passing ‘float’ for argument 1 to ‘void G4OpenGLQtViewer::rotateTheta(int)’ src/G4OpenGLQtViewer.cc:1579: warning: passing ‘float’ for argument 1 to ‘void G4OpenGLQtViewer::rotatePhi(int)’ Thank you, Andrea (gdb) bt #0 0x0000003522a30265 in raise () from /lib64/libc.so.6 #1 0x0000003522a31d10 in abort () from /lib64/libc.so.6 #2 0x00002b15c4c62200 in TerminationSignalHandler (sig=8) at /users/adotti/geant4.9.3_fpe_debug/source/global/management/include/G4FPEDetection.hh:90 #3 <signal handler called> #4 0x0000003cd94778e9 in ??
