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.
Please describe as succinctly as possible:
- What happened.
- What you thought should have happened.
- Precisely what you were doing at the time.
Please also include any C or lisp back-traces that you may have.

Dear Bug Team!
I was trying to write a regexp to find the next left parentheses not
in a comment. The following regexp does the job:
(re-search-forward "[^(;\n]*\\(\\(;.*\\)?\n[^(;\n]*\\)*(")
When I tried to use the shy grouping operator instead, ie.
(re-search-forward "[^(;\n]*\\(?:\\(?:;.*\\)?\n[^(;\n]*\\)*(")
it does not work. After playing around, the following is a simpler
regexp that shows the same behaviour
(re-search-forward ".*\\(\n.*\\)*") ;; goes to end of buffer
(re-search-forward ".*\\(?:\n.*\\)*") ;; goes to end of line
Experimenting further, it seems that having the `*' suffix
operator as the last element in a shy group, and again applying
the `*' operator to the group, is the construct that is problematic,
ie. \(?:<foobar>*\)*
Regards,
Stephen Kassner
