From 93646981011b0795329888bf7d2d10097e899432 Mon Sep 17 00:00:00 2001 From: Guido van Rossum Date: Fri, 26 Apr 2002 00:53:34 +0000 Subject: [PATCH] Make sure that tp_free frees the int the same way as tp_dealloc would. This fixes the problem that Barry reported on python-dev: >>> 23000 .__class__ = bool crashes in the deallocator. This was because int inherited tp_free from object, which uses the default allocator. 2.2.
