[Halld-offline] Crashes on Ubuntu 10.10 64bit

[David Lawrence]

Hi Beni,

     I found a solution to the crash problem you reported, but not a 
cause. This turns out
to be related to the ROOT TGeom package. If you look in the InitDRGeom 
method in
src/libraries/HDGEOMETRY/DRootGeom.cc there is a line that is commented 
out that
creates a new TGeoManager object. There are comments just above it in 
the code
indicating that it *should* be commented out on 64bit systems. This is 
clearly not the
case. I will work on tracking down the cause since at the moment, having 
it commented
out leads to crashes on some systems and having un-commented leads to 
crashes on others!

     For now, if you uncomment out this line so it actually creates the 
TGeoManager object,
things should start working for you.

Regards,
