21.5 freezes when reading large compressed files

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. Please describe as succinctly as possible: - What happened. - What you thought should have happened. - Precisely what you were doing at the time. Please also include any C or lisp back-traces that you may have. ================================================================ Dear Bug Team! When auto-compression-mode is effective, reading a large bzip2'ed file stalls XEmacs forever. As for 21.4.10, it doesn't. To reproduce: $ tst=`mktemp` $ dd if=/dev/urandom of=$tst bs=1024 count=1024 $ bzip2 $tst $ LANG=C xemacs-21.5-b9 -batch -vanilla \ -eval '(progn (auto-compression-mode 1) (find-file "'$tst.bz2'"))' Automatic file (de)compression is now ON. unbzip2ing tmp.XXXXWO6qV6.bz2... (...XEmacs freezes...) ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux aquair 2.4.19 #1 =e6=97=a5 8=e6=9c=88 18 20:28:51 JST 2002 i686 unknown unknown GNU/Linux ./configure '--with-mule' '--with-site-lisp' '--memory-usage-stats' '--pdump' '--use-kkcc' XEmacs 21.5-b9 "brussels sprouts" (+CVS-20021211) configured for `i686-pc-linux'.
