* Variety of small INC/DECREF patches that fix reported memory leaksJeremy Hylton2001-03-131-0/+1
| | | | | | | | | | | | | | | | | | | | | with free variables. Thanks to Martin v. Loewis for finding two of the problems. This fixes SF buf 405583. There is also a C API change: PyFrame_New() is reverting to its pre-2.1 signature. The change introduced by nested scopes was a mistake. XXX Is this okay between beta releases? cell_clear(), the GC helper, must decref its reference to break cycles. frame_dealloc() must dealloc all cell vars and free vars in addition to locals. eval_code2() setup code must INCREF cells it copies out of the closure. The STORE_DEREF opcode implementation must DECREF the object it passes to PyCell_Set().
