Martin Panter added the comment: Simpler test case, which might find a place somewhere like /Lib/test/test_memoryio.py:
>>> from io import BytesIO >>> b = BytesIO() >>> b.seek(1) 1 >>> b.readlines() # Should return an empty list Segmentation fault (core dumped) [Exit 139] The patch looks like the right approach. Just watch out for the indentation (tabs vs spaces). However I don’t see why we need the GET_BYTES_SIZE() macro or the (size_t) casting. Would it be okay comparing PyBytes_GET_SIZE() directly to self->pos? They are both meant to be Py_ssize_t. The bug looks like it was introduced by Serhiy’s changes in Issue 15381. ---------- nosy: +martin.panter _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24989> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
