Hello again,

A quick update in case anyone has been worried there is a weird bug in Geant. A few days after my report, I tried running my application on a different computer. It worked. Then I recompiled Geant on the machine on which I originally observed the problem - and now everything seems to be fine here too... Given the machine in question underwent a live system upgrade (a pretty major one too, skipping over several versions of the Linux distribution it runs) not long ago and the last time I compiled Geant on it was before the upgrade, I suspect the issue I observed was triggered by some weird library incompatibility. The bottom line: I still have got no idea what exactly the problem was, in particular why the segfault only happened on the SECOND re-use of world material - but at least it is gone now and more importantly, there seems to be nothing wrong with Geant itself.
