Amaury Forgeot d'Arc <amaur...@gmail.com> added the comment: There is a out-of-bounds error in Modules/_ctypes/libffi/src/x86/ffi64.c: at line 225, classes[i + pos] can go outside the allocated memory for classes (MAX_CLASSES=4). This code is not prepared to received "structures" with a small size (<32bytes) but where individual elements total more than 32bytes.
libffi support for unions is weak; at least ctypes should not use FFI_TYPE_STRUCT for unions. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14354> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
