try harder to avoid crashing when debug-printing -------------------- ChangeLog entries follow: -------------------- src/ChangeLog addition: 2010-01-18 Ben Wing <ben@xemacs.org> * lisp.h: * print.c: New variable `in_debug_print'. * alloc.c: * alloc.c (free_managed_lcrecord): If gc_in_progress and in_debug_print, just return instead of crashing. This only happens when the programmer calls debug_print() or a variation inside of a debugger, and is probably already diagnosing a crash. * print.c (struct debug_bindings): * print.c (debug_prin1_exit): * print.c (debug_prin1): At entrance, record the old value of in_debug_print in the debug_bindings, set up an unwind-protect to restore the old value, and set in_debug_print to 1. In the unwind-protect, restore the old value.
