[issue14752] Memleak in typeobject add_methods()

[Damien Cassou]

New submission from Damien Cassou <damien.cassou at gmail.com>:

In add_methods() function from typeobject.c, it looks like Py_DECREF is not called where it should be. Please find attached a patch that fixes the leak. The patch is also in commit #85a01718b3e3 of my hg repository under the branch fix_add_methods_leak.

This bug has been found using Coccinelle (http://coccinelle.lip6.fr/) and a dedicated semantic patch (https://gist.github.com/2634899).
