================================================================ Dear Bug Team! To reproduce, start in a context wherre the os-utils package is installed: xemacs -vanilla. Then M-x load-library RET jka-compr RET M-: (jka-compr-install) RET C-x C-f some-gzipped-file.gz RET I used the xemacs-truss.out.gz file that Thomas Mittelstaend sent yesterday, as well as a couple of other .gz's. All showed the symptom. ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux uwakimon 2.6.20.7 #2 SMP PREEMPT Tue Apr 24 21:32:05 JST 2007 x86_64 Dual Core AMD Opteron(tm) Processor 265 AuthenticAMD GNU/Linux ../configure '--with-mule' '--with-widgets=athena' '--with-dialogs=athena' '--with-athena=3d' '--with-bignum=gmp' '--with-database=none,berkdb' '--with-debug' '--with-error-checking=none' '--with-xft=emacs,tabs,gauges,menubars' '--with-union-type' '--with-system-packages=/usr/local/lib/xemacs' XEmacs 21.5-b28 "fuki" 2785829fe37c configured for `x86_64-unknown-linux'.
