Subject: 23.0.60; x-gtk-map-stock destroys match data
Date: Fri, 20 Jun 2008 14:38:25 +1200 (NZST)

In the event loop (?), update_frame_tool_bar calls x-gtk-map-stock (in
x-win.el) which uses string-match.  This changes the match data that I need for
my application.  I don't know what the rules are about using string-match from
C code but as a minimum x-gtk-map-stock should wrap save-match-data around
the call to it.

In edebug, if you use `e' you should be able to use match-beginning and
match-end.  But with M-: it's hopeless.

> Sorry but I don't know how to close the bug report.

Just send it to <bugnb>-close@... as I've done here.
