Dear all,

I am preparing the dch package for release 2.0. I have still a problem which I cannot fight myself.

In macros/dch I put a set of macros for:
* simulation runMC.C
* digitisation makeDigi.C
* ideal hit reconstruction makeIdealHits.C

I am able to run all of them, but when I am trying to close root afterwards I get segmentation violations. The output data seem to be not affected - results look reasonable.
I suspect it has something to do with the way I handle geometry, because TGeoManager appears in the backtrace. Hopefully Tobias or Mohammad are able to help me? Others are welcome, as well Smile

Thanks in advance,

Here you are the backtrace from quitting root after execution of runMC.C (others are very similar):

root [1] .q
WARNING - Attempt to delete the physical volume store while geometry closed !
WARNING - Attempt to delete the logical volume store while geometry closed !
WARNING - Attempt to delete the solid store while geometry closed !
WARNING - Attempt to delete the region store while geometry closed !
