Alternatively I could fix our signal handler for Solaris Sparc, so that it looks at the stack and if it finds a Fskip_syntax_* frame prints a completely different message :-) Incidentally is there any reason why we do not try to print some kind of C stacktrace from our signal handler? The Sun Workshop version did that and sometimes it was really helpful. Obviously this would be somewhat platform specific but I think at least for Solaris and linux/glibc it should be easy (didn't Ulrich post something about that some time ago?). I guesstimate that about 80% of our users use either Solaris or Linux, so it would definitely be worthwhile. In that case they should complain to their sysadmin in the first instance. true, but If you use the Help->Submit Bug Report menu the report is send to xemacs(a)xemacs.org. Maybe some people don't realise that this is a mailing-list/newsgroup. Gunnar -- Gunnar Evermann Speech, Vision & Robotics Group Engineering Department Cambridge University
