Repeated below is the crash report I filed earlier today, along with the LISP traceback, which may be of some use... I notice that I get the same crash with xemacs 21.1.12, 21.4.3, and 21.4.5. I notice that I DON'T get the crash if I mis-name the directory /usr/local/lib/xemacs-21.x.x. -Ron Cohen- ----------------------------------------- xemacs (21.4.5) seems to reliably crash when reading vm mail with too-long a recipient list. This is on a Mac G4 running OS 10.1.2. [1] Segmentation fault xemacs -f vm [cohen2m3:~] rcohen% Fatal error (11). Unfortunately the crash produces a segmentation fault but no CORE file, so I cannot provide a backtrace. It doesn't seem to matter whether the characters are in the "To" field or the "CC" field. The incoming mail file that produces a crash has something like 4175 characters in the To: field. Cutting that number down to 4172 results in no crash. Replacing the three deleted characters with anything else on the keyboard restores the crash. uname -a: Darwin cohen2m3.llnl.gov 5.1 Darwin Kernel Version 5.1: Tue Oct 30 00:06:34 PST 2001; root:xnu/xnu-201.5.obj~1/RELEASE_PPC Power Macintosh powerpc ./configure XEmacs 21.4.5 "Civil Service" configured for `powerpc-apple-darwin5.1'.
