Ar an séiú lá de mí na Nollaig, scríobh Stephen J. Turnbull: See specifier.c:1342, setup_charset_initial_specifier_tags for where this can happen. The crash didn’t happen if define-specifier-tag had been called at least once with a third argument, which is why I found it difficult to reproduce; fortunately, I regularly use a TTY build, where using the charset predicate is a waste of time in lots of ways, and managed to reproduce it consistently today. Building with this patch eliminates that crash. Steve, I unsubscribed from xemacs-patches as an experiment to see if that woul eliminate the duplicated messages I was getting from it. I then sent 17785.27430.262538.827891(a)parhasard.net to it, which has yet to appear--is it currently subscriber-only? I suppose I’ll see whether this appears. src/ChangeLog addition: 2006-12-08 Aidan Kehoe <kehoea(a)parhasard.net&gt; * specifier.c (charset_matches_specifier_tag_set_p): A charset's entry in Vcharset_tag_lists may be nil, if, when that charset was created, no tags with associated charset predicates existed. Accept this posibility, treat it as the tag not matching that charset.
