New submission from Cubi <dennis-da...@protonmail.com>:
String buffers are not freed when pointers to them (created via ctypes.cast) are deleted, even though those pointers hold references to the string buffer (in tagCDataObject.b_objects, I think). Code examples can be found on StackOverflow.com [1]. Thanks to Mark Tolonen's answer on that StackOverflow post we know that it is a refcount problem. Tested in Python v3.7.4 x64 on Windows 10 x64, and in Python v3.8.2 x64 on ArchLinux x64 (5.6.7-arch1-1) [1] https://stackoverflow.com/q/61479041 ---------- components: ctypes messages: 367549 nosy: cubinator priority: normal severity: normal status: open title: Refleak in CDataObject type: resource usage versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40425> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
