================================================================ Dear Bug Team! XEmacs crashes when trying to view a buffer that contains some strange binary (i.e. non-roman) characters in it. It crashes and prints out the following message: Fatal error: assertion failed, file /usr/src/xemacs-21.4.19/src/redisplay-msw.c, line 563, runs[i].dimension == 1 Aborted (core dumped) I first saw this bug when I had received some SPAM email containing Chinese or Japanese characters in it, and was reading the mail using Gnus. It would cause Xemacs to crash when trying to display the article summary buffer in Gnus (which I assume was trying to display the Subject line). When composing this bug report, I've discovered that it is not just a problem in Gnus, but it will also cause xemacs to crash when simply editing a buffer with those characters in it. Below is a uuencoded example of a file that triggers the bug. I had to uuencode it so it won't crash emacs when I tried to insert it; uudecode it before testing. To reproduce the bug, simply try to visit the file. It is expected that xemacs will simply display the file in a buffer, but it crashes instead. Thanks. ---cut here--- begin 644 bad-data.dat M0V]N=&5N="U4>7!E.B!T97AT+W!L86EN.PH)8VAA<G-E=#TB:7-O+3(P,C(M M:G`B"D-O;G1E;G0M5')A;G-F97(M16YC;V1I;F<Z(#=B:70*"ALD0B$A-UHD M)#4D.WTD021'-VLZ)R0W)#\D8B1.)$XA(D)＠-GXD2DMH1GPD2S4_3&0D<CM] M)$$[3R1A)$8D)"1K/&=)6"0_)$$A1"0])"8D)"0F/7=`+21/(2(P1C,P/W1" M/R0O)"0D:R1B)$XD1R0Y(2,;*$(*"ALD0B5&)6PE+R5I)&0A(B5$(3PE-R5G M)4,E2"1+)4DE0R57)6HD3B1A)&HY?B1S)$<D)"1#)#\]=T`M)#\D021.0F=( M/B0L(2(_33I*)$`D0R0_)&＠D)B1+(2(]4#)Q)"0E-24D)4＠D8B4U)2\E:20X M)&,D2B0D/7=`+21/)#\D)"0L)"0_33I*(2HU521+(2)+7$5V)$X]=T`M)"P] M4#)Q)"0E-24D)4＠D<CM()"9-?4TS)'(Y320H)$8D7R1&,CPD-20D(2,_33I* M)$Y"/B1+/5`R<20D)$LZ)"1K/7=`+21*)',D1B0B)',D7B1J-6\D2B0D)$＠[ 15R0D)%XD.R1S)"LA*1LH0＠H` ` end ---cut here--- ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: CYGWIN_NT-5.1 vzell-de 1.5.19(0.150/4/2) 2006-01-20 13:28 i686 Cygwin /usr/src/xemacs-21.4.19/configure '--pdump' '--srcdir=/usr/src/xemacs-21.4.19' '--prefix=/usr' '--datadir=/usr/share' '--statedir=/var' '--libdir=/usr/lib' '--infodir=/usr/share/xemacs-21.4.19/info' '--mandir=/usr/share/man/man1' '--package-path=/usr/local/share/xemacs/site-packages:/usr/share/xemacs/site-packages:/usr/share/xemacs/xemacs-packages:/usr/share/xemacs/mule-packages' '--with-mule' '--with_file_coding=yes' '--with_msw=yes' '--with-modules=no' '--with-athena=3d' '--with-widgets=lucid' '--with-dragndrop' '--with-offix' XEmacs 21.4.19 "Constant Variable" configured for `i686-pc-cygwin'.
