Vinay Sajip added the comment: The test checks that a structure passed by value is indeed passed by value - something that is architecture-dependent, as calling conventions differ across architectures.
If the test fails, this indicates that the structure isn't being passed by value - a pointer to the structure is probably passed, which is pass-by-reference rather than pass-by-value. This indicates that a change to ctypes or libffi is needed to fix this. See the changes made in Modules/_ctypes/libffi_msvc/ffi.c for bpo-29565 - probably, analogous changes need to be made to the corresponding code for arm64. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29804> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
