New submission from s-wakaba: When compiling cpython with specifying NSMALLPOSINTS and NSMALLNEGINTS macros as zero to skip making small_ints[] array, like following command, process couldn't finish.
$ ./configure CPPFLAGS='-DNSMALLPOSINTS=0 -DNSMALLNEGINTS=0' $ make The reason looks a problem that PyLong_FromLong(0) returns irregular int object: Py_SIZE(zero_int) must be 0, but it becomes 1. maybe this problem never appears in actual cases, but in "longobject.c", it still looks supported to compile without small_ints[]. I don't know it should be fixed or not. but, as a result, I could compile cpython after addition of one line like attached patch. Could you confirm this point? Thanks. ---------- components: Interpreter Core files: longobject.c.patch keywords: patch messages: 251436 nosy: s-wakaba priority: normal severity: normal status: open title: PyLong_FromLong() potentially returns irregular object when small_ints[] isn't used type: behavior versions: Python 3.5 Added file: http://bugs.python.org/file40555/longobject.c.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25221> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
