[issue16050] ctypes: callback from C++ to Python fails with Illegal Instruction call
R. David Murray added the comment: Arnon also checked that our local copy of libffi contains the upstream fix. In the absence of a way to test this, we'll just have to assume it is fixed. -- nosy: +r.david.murray resolution: - out of date stage: - resolved status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16050 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue16050] ctypes: callback from C++ to Python fails with Illegal Instruction call
Arnon Yaari added the comment: libffi seem to have fixed this issue in their commit 4acf005 - Build fix for soft-float power targets. The fix is different than what Pavel suggested, but sounds like it should do the same. -- nosy: +wiggin15 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16050 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Jesús Cea Avión added the comment: Pavel, I think the FFI we use is a direct copy of libffi.

[issue16050] ctypes: callback from C++ to Python fails with Illegal Instruction call
New submission from Pavel Maltsev: ppc_405, Linux 2.4, GCC 3.3.1 Python crashes on attempt to pass python callback function to custom C++ library under PowerPC 405. This happens because some versions of GCC (I guess below 4.1) doesn't raise __NO_FPRS__ flag if hard-floats is not supported, instead they use _SOFT_FLOAT. So we need to change #ifndef __NO_FPRS__ to #if (!defined(__NO_FPRS__) !defined(_SOFT_FLOAT)) -- components: ctypes files: soft_float.patch keywords: patch messages: 171325 nosy: Opilki_Inside priority: normal severity: normal status: open title: ctypes: callback from C++ to Python fails with Illegal Instruction call type: crash versions: Python 2.7 Added file: http://bugs.python.org/file27309/soft_float.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16050 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
