Because the original backtrace reported by Drew said this: Exception 0xc0000005 at this address: 0115f769 Backtrace: 01200a23 01200a94 ... This is the exception handler installed by w32fns.c at work (see my_exception_handler and globals_of_w32fns), and "Exception 0xc0000005" is invalid address exception (a.k.a. SIGSEGV). > > Stefan, could this be related to your latest changes in intervals.c? > > Could be, but we'd need more of the backtrace to figure out > what's happening. The only way to have more of the backtrace is to run Emacs under GDB to begin with. Without that, when Emacs hits a fatal exception like that, one address is all you got.
