================================================================ Dear Bug Team! After a number of changes to my configure script to get past a Bus Error after dumping (in update-elc-2.el), I finally tracked the potential problem down to recent revisions of split-string. Unfortunately, I can't get a stack trace or anything useful because XEmacs exits as soon as it loads (even xemacs -vanilla) on my platform. Reverting lisp/subr.el to the latest pre CVS20030423 version fixes the crash. Note I have --use-union-type defined, but compiling with that off did not help. However, compiling with --debug=yes fixed the problem. Does dbugging on affect the stack or function calls? I ask because most of the early load Bus errors I have seen on this system with XEmacs were stack related and occured in regex code. I have an 8MB stack. ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Darwin grendal.frinabulax.org 6.5 Darwin Kernel Version 6.5: Mon Apr 7 17:05:38 PDT 2003; root:xnu/xnu-344.32.obj~1/RELEASE_PPC Power Macintosh powerpc ./configure '--with-mule' '--with-widgets=athena' '--with-xfs' '--with-dialogs=athena' '--error-checking=none' '--debug=no' '--package-path=/usr/local/sbin/xemacs/lib' '--prefix=/usr/local/sbin/xemacs' '--with-prefix' '--with-sound=noesd' '--cflags=-O3 -no-cpp-precomp' '--pdump' '--with-ldap=no' '--use-union-type' '--with-xmu' XEmacs 21.5-b11 "cabbage" (+CVS-20030423) configured for `powerpc-apple-darwin6.5'.
