Gunnar Evermann <Gunnar.Evermann(a)nats.informatik.uni-hamburg.de&gt; writes in xemacs-beta(a)xemacs.org: It's Mule related. I've tried four configurations. XEmacs/No-Mule and XEmacs/Mule-20.4 don't crash. XEmacs/Mule-21 with distribution .elcs (the ones in the -elc tarball on the FTP site bytecompiled with a tty-only XEmacs/No-Mule), and XEmacs/Mule with core .elcs bytecompiled with XEmacs/Mule. Both of the Mule builds crash in the same place. Hmm. Maybe I should try a Mule build without minimal tagbits. #0 0x817ac57 in print_internal (obj={gu = {type = Lisp_Type_Record, val = 0}, s = {bits = 0, val = 0}, u = {bits = 0, val = 0}, ui = 0, i = 0,
