@methane, thanks for your PR! By analyzing the history of the files in this pull request, we identified @benjaminp, @Haypo, @serhiy-storchaka, @1st1 and @tim-one to be potential reviewers. |
When LOAD_METHOD is used for calling C mehtod, PyMethodDescrObject was passed to profilefunc from 5566bbb. But lsprof traces only PyCFunctionObject. Additionally, there can be some third party extension which assumes passed arg is PyCFunctionObject without calling PyCFunction_Check(). So make PyCFunctionObject from PyMethodDescrObject when tstate->c_profilefunc is set.
