This is almost more alarming than a potential bug in vfs_object_create- as the difference between the config file I was using should not cause this. *I* sure can't spot what config option might be different. I also had done a complete removal of the build directory and complete fresh build of GPLUS. (sounds of hair tearing). Can anyone suggest what below might have caused this breakage? --- GENERIC Mon Feb 5 11:46:37 2001 +++ GPLUS Mon Mar 12 14:59:09 2001 @@ -19,56 +19,57 @@ # # For hardware specific information check HARDWARE.TXT #
