In the destractor definition for the G4Allocator in global/management/include/ G4Allocator.hh, the memory reagion "aPage" has to be released by using delete () function instead of free() function. Because of this bug, Geant4.2.0 does always terminate itself with "segmentation violation" crash. This bugfix was reported in a Geant4 Users meeting in Japan, 20 December 2000, by myself. Regards
Thanks for pointing us to this potential problem. The fix will be introduced soon.
Bug fixed in tag "global-V03-00-00". Submitted to system test.
