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.
