New submission from Maxime Belanger: Greetings,
We're compiling a custom version of Python 2.7.9 for the Mac (building on OS X 10.9 with Xcode 6.1), and we're instructing Python to use a vanilla copy of `libffi` (that we've also compiled ourselves) using the `--with-system-ffi` flag. We're running the regression test suite for sanity purposes and we've noticed this error in `test_ctypes`'s `test_longdouble` method: ====================================================================== FAIL: test_longdouble (ctypes.test.test_callbacks.Callbacks) ---------------------------------------------------------------------- Traceback (most recent call last): File "../Python.framework/Versions/2.7/lib/python2.7/ctypes/test/test_callbacks.py", line 88, in test_longdouble self.check_type(c_longdouble, 3.14) File "../Python.framework/Versions/2.7/lib/python2.7/ctypes/test/test_callbacks.py", line 24, in check_type self.assertEqual(result, arg) AssertionError: 0.0 != 3.14 I'm reasonably convinced this is caused by the version of `libffi` we're using. It seems that if the `--with-system-ffi` flag isn't set, an internal version of `libffi` is used instead. However, given that version 3.1 is said to be the version Python 2.7.9 is "tracking", this feels like a bug to me. Also, it seems that trying to hit this code path in production code could trigger a crash. ---------- components: Tests, ctypes messages: 236729 nosy: Maxime Belanger priority: normal severity: normal status: open title: `test_longdouble` fails on Mac when using system libffi (version 3.1) type: crash versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23534> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
