In the destructor of G4MaterialPropertiesTable there is a print out of the pointer in a map before being deleted. This is unnecessary and a little confusing when it crops up in applications. geant4/source/materials/src/G4MaterialsPropertiesTable.cc - line 71 for (i = MPT.begin(); i != MPT.end(); ++i) { G4cout << (*i).second << G4endl; delete (*i).second; } Just a minor output fix. Only in Geant4.10.03. Cheers!
Thanks for reporting this. The fix will be included in the next patch release.
