[Bug: 21.4.12] Inf-loop using replace-in-string

================================================================ Dear Bug Team! After `M-: (replace-in-string "xe" "\\(x\\)?" "") RET', XEmacs 21.4.12 seems to get into an infinite loop. After `M-x toggle-debug-on-quit RET' and `C-g', I get: ,---- | Signaling: (quit) | string-match("\\(x\\)?" "e" 0) | replace-in-string("xe" "\\(x\\)?" "") | eval((replace-in-string "xe" "\\(x\\)?" "")) | #<compiled-function (expression &optional | eval-expression-insert-value) "...(18)" | [eval-expression-insert-value expression values eval prin1 t] 3 | 814530 (list (read-from-minibuffer "Eval: " nil read-expression-map | t ...) current-prefix-arg)>((replace-in-string "xe" "\\(x\\)?" "") | nil) | call-interactively(eval-expression) `---- expression "\\(x\\)?" should not be valid. [ I apologize in case this has already been fixed in more recent versions of XEmacs. (I don't want to upgrade this XEmacs installation, as I only use it for testing/reference; I'm using GNU Emacs normally.) ] Bye, Reiner. ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux lumberjack 2.4.20-64GB-SMP #1 SMP Mon Mar 17 17:56:03 UTC 2003 i686 unknown unknown GNU/Linux ./configure '--prefix=/import/xtra/emacs/xemacs-21.4.12' '--with-msw=no' '--with-mule=yes' XEmacs 21.4.12 "Portable Code" configured for `i686-pc-linux'.
