Greetings, and thanks for the report! This was put in as a crude first measure to remove error conditions arising from within the error handler itself, usually in certain extreme circumstances such as memory exhaustion, etc. When this would happen, an endless loop of identical and nested error invocations would be displayed immediately before core dump. If memory served, many of these instances pertained to string manipulation, printing, and memory allocation. Obviously, the right way to do this is to put a recursion catcher in front of each call, not inside the error handler itself, but I don't know how to make the former work in a lisp system where various layers of user code calling the error handler can freely pile on top of one another. The other obvious option is to forsake general protection against infinite error recursion, and attempt to track down each specific instance where such a phenomenon can be created in the lowest level C code, asymptotically at best approaching a solution.
Do you have any recommendations here? I've even lost the previous bug reports showing how to trigger the error recursion, so I don't know where to begin to test.
