Hi,
this might be a bug.
re-search-backward never returns in the following expression:
(with-temp-buffer
(insert "new Test1() { public void f(final int i)")
(re-search-backward "\\([a-z (]*\\)*ne" (point-min) t))
I'm using
GNU Emacs 21.3.1 (i386-msvc-nt4.0.1381) of 2003-03-28 on buffy
Regards,
Martin

(re-search-backward "\\([a-z (]*\\)*ne" (point-min) t))
The problem is a repetition operator inside a repetition operator.
That regexp can match the null string in infinitely many different
ways, so it causes an infinite loop.
