It's almost as simple as it gets:

Step 1:  Launch Gate with argument --qt

Step 2: Use the following commands.

/vis/open OGLSQt
/vis/drawVolume



Cheers,
Marc

Hi,

can you give us the most minimal macro who shows this behaviour ?

Hi everyone,

With Gate 6.2 on OS X 10.9, I'm experiencing another Qt-related crash. I've already used the fix provided by Jérôme back in December (seehttp://article.gmane.org/gmane.comp.science.opengate.user/3434/match=jérôme+qt+os+x+10.9<http://article.gmane.org/gmane.comp.science.opengate.user/3434/match=j%C3%A9r%C3%B4me+qt+os+x+10.9>).

The crash happens after launching Gate with the --qt option and using the command /vis/drawVolume (or /vis/sceneHandler/attach).

I've included the backtrace below:

I realize this might be more of a Geant4 bug than anything, but if someone has experienced this and has a fix for it, I'd appreciate the help.

Cheers,
