Hi xiang,


I have already patched our build environment with the fix and tested it locally. Although I cannot test it in production, have taken out the code of new_weakref, init_weakref and clear_weakref from weakrefobject.c. Changed init_weakref to initialize wr_prev and wr_next with NULL and verified that test program does crash after fix.
