It can also crash. ast.literal_eval('+0'10*6) The cause is that all AST handling C code (in particularly converting the AST from C to Python) is recursive, and therefore can overflow the C stack. Some recursive code has arbitrary limits which cause raising exceptions like MemoryError in the initial example, but not all code has such checks.
