Clang sets the class->info field to values different from 0x1 or 0x2 (the only allowed values in the traditional GNU Objective-C runtime ABI) to store some additional information, but this breaks backwards compatibility. Wipe out all the bits in the fields other than the first two upon loading a class. Modified: branches/gcc-4_6-branch/libobjc/ChangeLog branches/gcc-4_6-branch/libobjc/init.c
