STINNER Victor added the comment: With the development version (Python 3.5), I reproduce the crash when Python is compiled in debug mode:
$ ./python astlinenotest.py python: Python/compile.c:3975: assemble_lnotab: Assertion `d_lineno >= 0' failed. Abandon (core dumped) The problem is that astlinenotest.py creates an AST node without lineno information, which makes an assertion to fail in the compiler. In my astoptimizer project, I use this function to not have to worry of the lineno: def copy_lineno(node, new_node): ast.fix_missing_locations(new_node) ast.copy_location(new_node, node) return new_node ---------- nosy: +haypo title: Compiling modified AST crashes on debug build unless linenumbering discarded -> in debug mode, compile(ast) fails with an assertion error if an AST node has no line number information _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21385> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
