reenabling gutter caused core dump

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. In XEmacs 21.2 (beta19) "Shinjuku" [Lucid] (i686-pc-linux, Mule) of Wed Sep 29 1999 on buck configured using `configure --prefix=/opt/local --with-mule' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: I don't usually use gutter, so I'm disabling it with (set-specifier default-gutter-visible-p nil) When I opened a lot of files, I thought it might be usefult to have gutter again. So, I enabled gutter with (set-specifier default-gutter-visible-p t) and typed C-x b. Then XEmacs dumped core. This one is build from CVS and xemacs/src/CVS/Entries says, /ChangeLog/1.154.2.235/Wed Sep 29 07:20:36 1999//Trelease-21-2 Lisp backtrace and output of `where' follows. -- Yoshiki Hayashi
