New submission from Giuseppe Ottaviano <[EMAIL PROTECTED]>: Hi all, trying to compile Python 2.6 I got a segmentation fault while byte-compiling the modules.
The segmentation fault happened in ast_for_atom, parsing an Unicode entity. I found out that another problem prevented unicodedata to be imported, so unicode_decode raised an exception. I think the problem is in the following lines: if (PyErr_ExceptionMatches(PyExc_UnicodeError)){ PyObject *type, *value, *tback, *errstr; PyErr_Fetch(&type, &value, &tback); errstr = ((PyUnicodeErrorObject *)value)->reason; I'm not an expert of CPython internals, but the exception is raised with PyErr_SetString, so value is a PyStringObject, and that cast is invalid. Changing the last line to errstr = value; everything works. The patch is attached. ---------- files: ast.patch keywords: patch messages: 76119 nosy: ot severity: normal status: open title: Patch for segmentation fault in ast_for_atom type: crash versions: Python 2.6 Added file: http://bugs.python.org/file12075/ast.patch _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue4367> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
