Re: Eureka!

Ben> This looks to be a fix for all crashes involving Ben> condition_case_unwind(), and the finger gets pointed at At first I thought this patch worked for me, and indeed it did, when I left the debug-on-entry in my .eudc-options. This used to crash xemacs every time. However, when I took that out and tried it again, xemacs crashed. The lisp backtrace and C backtrace are appended. I guess I'll have to turn always_gc on and see what happens. Bummer.
