Description gum 2006-09-14 17:19:56 CEST

As reported by amaresh kumar in the "Examples Forum" the LXe example core dumps
on startup.

Comment 1 gum 2006-09-14 17:32:59 CEST

Set the pointers to G4MaterialPropertiesTable LXe_mt and MPTPStyrene to NULL in
the class constructor of LXeDetectorConstruction. This fixes the core dump in
method SetDefaults at:

  if(LXe_mt)LXe_mt->AddConstProperty("SCINTILLATIONYIELD",12000./MeV);
  if(MPTPStyrene)MPTPStyrene->AddConstProperty("SCINTILLATIONYIELD",10./keV);

on program start-up
