Subject: bootstrap non-fatal args-out-of-range error making autoloads
Date: Thu, 24 Sep 2009 18:38:49 -0400

When bootstrapping the current trunk, I see the following non-fatal
error during the build:

Generating autoloads for dired-aux.el...
Error: (args-out-of-range 0 0)
Generating autoloads for dired-x.el...

Turning on debug-on-error while making autoloads gives (after some
randomness) the following backtrace. (I don't know why it is
abbreviated, I am setting print-length and friends to nil). This is
from the point of the find-file-noselect call in
autoload-find-destination.

It looks like something is messing up the match-data in
vc-cvs-parse-entry. It's not obvious to me that requiring parse-time
and calling parse-time-string isn't going to change the match-data in
some way.
