[Bug XEmacs-21.4.5] regexp matching won't always work

Hi, I got the following strange behaviour in the regexp matching on both XEmacs/Mule on HP-UX and XEmacs on Windows-NT: the only difference is \\(ab\\|dg\\)\\| vs ab\\|dg\\| at the beginning... (let ((re "\\(\\(\\.\\(\\(ab\\|dg\\)\\|[ch]\\(\\+\\+\\|pp\\|c\\|h\\|xx\\)?\\|tex\\(i\\(nfo\\)?\\)?\\|el\\|emacs\\|l\\|lsp\\|p\\|java\\|f\\(90\\|77\\|or\\)?\\|ada\\|p[lm]\\|tcl\\|m\\|scm\\|pm\\|py\\|g\\|s?html\\|ma?k\\)\\)\\|\\([Mm]akefile\\(\\.in\\)?\\)\\)$")) (cons (string-match re "sb-image.el") (string-match re "sb-ant.el"))) => (nil . 6) (let ((re "\\(\\(\\.\\(ab\\|dg\\|[ch]\\(\\+\\+\\|pp\\|c\\|h\\|xx\\)?\\|tex\\(i\\(nfo\\)?\\)?\\|el\\|emacs\\|l\\|lsp\\|p\\|java\\|f\\(90\\|77\\|or\\)?\\|ada\\|p[lm]\\|tcl\\|m\\|scm\\|pm\\|py\\|g\\|s?html\\|ma?k\\)\\)\\|\\([Mm]akefile\\(\\.in\\)?\\)\\)$")) (cons (string-match re "sb-image.el") (string-match re "sb-ant.el"))) => (8 . 6) BTW, I'll submit a patch to Eric Ludlam for speedbar-0.14beta2... (basically to get my patch to XEmacs from 1999-08-26 back -- my own fault not to realize the "probably"...). - Christoph
