be more careful when printing to check for bad objects -------------------- ChangeLog entries follow: -------------------- src/ChangeLog addition: 2010-01-13 Ben Wing <ben@xemacs.org> * print.c: * print.c (internal_object_printer): * print.c (enum printing_badness): * print.c (printing_major_badness): * print.c (print_internal): Clean up the part of the code that looks for things that might lead to crashing in the print code: -- Make the "badness" messages more consistent. -- Move the checks for circularities after the checks for bad memory, since the checks for circularities involve accessing memory (which could be bad). -- Add an extra check to see if the object's implementation structure is bad memory. -- Add extra check for object itself being a null pointer or implementation pointer being null. -- Add some extra comments to help in maintaining the code.
