This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing
list,
and to the gnu.emacs.bug news group.

bars)

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:



Hi.  Loading the text file in the attached gzip file deterministically
causes my emacs to hang.  Even (keyboard-quit) won't interrupt it. A
quick look with gdb suggests it's the regexp code that's at fault.
I've trimmed the file down to something close to the minimal
fault-revealing sequence.

Let me know if you need more info.

cheers
alan

Actually, this is closer to the minimal fault-revealing example.  All
spaces are spaces (not tabs).  Whitespace IS significant.  I hope this
helps.

It does not fail for me in the current Emacs sources from CVS.
Does it fail for you in that version?
