================================================================ Dear Bug Team! Loading with xemacs -vanilla, some straaaaange stuff happens when doing searches. I believe the behavior is also found in 21.5.11. The best way to describe it is with a script: 1) Load the following into a buffer called junk: ---start # ======================================================================= # $Source$ # $Revision$ # $Date$ # $Author$ # $Name$ - the cvs tag, if any # $State$ # $Locker$ # ======================================================================= /* ----------------- amb_foooo_foooo_rtgsonly ----------------- */ delete_job: amb_foooo_foooo_rtgsonly insert_job: amb_foooo_foooo_rtgsonly job_type: b permission: gx,mx,me # ======================================================================= # $Source$ # $Revision$ # $Date$ # $Author$ # $Name$ - the cvs tag, if any # $State$ # $Locker$ # ======================================================================= /* ----------------- amc_foooo_foooo_rtgsonly_req ----------------- */ delete_job: amc_foooo_foooo_rtgsonly_req insert_job: amc_foooo_foooo_rtgsonly_req job_type: c box_name: amb_foooo_foooo_rtgsonly command: /fo/ffooo/foo/fooooooooooooooooooooooo --univ_rule 'universe_bloom_rtgsonly' ---end 2) Make sure the window is narrow enough to cause wrap-around. 72 columns wide should do it, which is the width of the equal signs in the cvs headers. 3) CTLR-s (for Isearch) rtgs. Finds first one. 4) CTRL-s. Finds next one. 5) Hit a left cursor key. Cursor jumps one back. 6) Keep searching until you get to a rtgs that is beyond the arrow. 7) Hit a left cursor key. Cursor jumps one back. 8) Go to top of buffer. 9) switch to *scratch* buffer 10) Type in (custom-set-variables '(truncate-lines t)) 11) With cursor at end of line, evaluate by CTRL-x CTRL-E 12) Switch back to buffer junk. The wrap-around should now be truncated with straight arrows. 13) Repeat 3,4,5,6 14) When you repeat 7, the cursor jumps back to the starting point of the search NOT the previous character. 15) Split the window in two. Set one window to *scratch* the other to junk 16) Get into the junk window. 17) Go to top of buffer. 13) Repeat 3,4,5,6 14) When you repeat 7, the cursor moves one character back, but you get the following in *Warnings* (2) (command/warning) Error in `pre-command-hook' (resetting to nil): (invalid-change (Deletion of this object not currently permitted #<window on "amb_midss_bloom_rtnsonly.jil" 0x14f1>)) Backtrace follows: # bind (inhibit-quit) delete-window(#<window on "amb_midss_bloom_rtnsonly.jil" 0x14f1>) # bind (next window window) window-reduce-to-one(#<window on "*Warnings*" 0xa7a>) # bind (combination-start root-window frame) frame-reduce-to-one-window(#<mswindows-frame "emacs" 0xa79>) # bind (configuration frame) really-set-window-configuration(#<mswindows-frame "emacs" 0xa79> [cl-struct-window-configuration #<mswindows-frame "emacs" 0xa79> 534 754 #<buffer "amb_midss_bloom_rtnsonly.jil"> 14 0 0 [cl-struct-saved-window nil nil nil nil nil nil nil 0 0 534 685 0 0 nil nil [cl-struct-saved-window nil nil t #<buffer "*Warnings*"> #<marker in no buffer 0x23b0594> #<marker at 1 in *Warnings* 0x23b0564> #<marker at 1 in *Warnings* 0x23b057c> 0 0 534 342 0 0 nil nil nil [cl-struct-saved-window t nil nil #<buffer "amb_midss_bloom_rtnsonly.jil"> #<marker at 1158 in amb_midss_bloom_rtnsonly.jil 0x23b054c> #<marker at 586 in amb_midss_bloom_rtnsonly.jil 0x23b051c> #<marker at 997 in amb_midss_bloom_rtnsonly.jil 0x23b0534> 0 342 534 685 0 0 nil nil nil nil]] [cl-struct-saved-window nil t nil #<buffer " *Minibuf-0*"> #<marker at 1 in *Minibuf-0* 0x23b05dc> #<marker at 1 in *Minibuf-0* 0x23b05ac> #<marker at 1 in *Minibuf-0* 0x23b05c4> 0 685 534 699 0 0 nil nil nil nil]]]) # bind (frame configuration) set-window-configuration([cl-struct-window-configuration #<mswindows-frame "emacs" 0xa79> 534 754 #<buffer "amb_midss_bloom_rtnsonly.jil"> 14 0 0 [cl-struct-saved-window nil nil nil nil nil nil nil 0 0 534 685 0 0 nil nil [cl-struct-saved-window nil nil t #<buffer "*Warnings*"> #<marker in no buffer 0x23b0594> #<marker at 1 in *Warnings* 0x23b0564> #<marker at 1 in *Warnings* 0x23b057c> 0 0 534 342 0 0 nil nil nil [cl-struct-saved-window t nil nil #<buffer "amb_midss_bloom_rtnsonly.jil"> #<marker at 1158 in amb_midss_bloom_rtnsonly.jil 0x23b054c> #<marker at 586 in amb_midss_bloom_rtnsonly.jil 0x23b051c> #<marker at 997 in amb_midss_bloom_rtnsonly.jil 0x23b0534> 0 342 534 685 0 0 nil nil nil nil]] [cl-struct-saved-window nil t nil #<buffer " *Minibuf-0*"> #<marker at 1 in *Minibuf-0* 0x23b05dc> #<marker at 1 in *Minibuf-0* 0x23b05ac> #<marker at 1 in *Minibuf-0* 0x23b05c4> 0 685 534 699 0 0 nil nil nil nil]]]) # bind (found-start found-point inhibit-quit edit nopush) isearch-done() isearch-pre-command-hook() # (unwind-protect ...) # (catch #<INTERNAL OBJECT (XEmacs bug?)
