crash when loading file which contains EUC-JP and ISO-2022-JP

Save the following attached file: (This file is only gzipped, because Gnus runs into an endless loop when I attach it without gzipping. That is probably also a bug, but a different one.). Gunzip it, start XEmacs and let it load this file: mfabian＠gregory:~/xemacs-bug$ LANG=ja_JP xemacs -q -vanilla kanji.euc-iso Fatal error (11). Your files have been auto-saved. Use `M-x recover-session' to recover them. It is important to use "LANG=ja_JP", it will not happen with "LANG=C". The file "kanji.euc-iso" contains only two lines. Both lines contain only the Japanese word "漢字" (Kanji). The first line contains this word in EUC-JP encoding, the second line in ISO-2022-JP encoding. The order of these lines is also important, if the ISO-2022-JP line comes first like in the gunzipped version of this file: XEmacs will not crash (but of course the EUC-JP part is unreadable). I encounter this problem often when opening Japanese *.patch files, which often contain both EUC-JP in some hunks and ISO-2022-JP in other hunks. If the EUC-JP comes first, XEmacs will crash. I use the following XEmacs version: In XEmacs 21.1 (patch 10) "Capitol Reef" [Lucid] (i686-pc-linux, Mule) of Mon May 8 2000 on nozomi configured using `configure --prefix=/opt/stow/xemacs-21.1.10 --with-mule=yes --with-dialogs=athena3d --with-xface=yes --with-wnn=yes --with-canna=yes --with-xim=xlib --with-xfs --with-menubars=lucid --site-includes=/opt/include --site-libraries=/opt/lib '--cflags=-g -O4 -fno-strength-reduce'' (The same problem also occurs with the XEmacs 21.1.12 from the SuSE rpm).
