Comment 3 David Kilzer (:ddkilzer) 2007-11-25 11:44:58 PST
This is a regression from shipping Safari 3.0.4 (523.12) with original WebKit on Mac OS X 10.4.11 (8S165).  (The page doesn't work, but loading it doesn't crash.)

Comment 4 David Kilzer (:ddkilzer) 2007-11-25 12:08:30 PST
The bisect-builds script reports:
Works: r27761  Fails: r27811

Comment 5 David Kilzer (:ddkilzer) 2007-11-25 13:12:22 PST
A delta <http://delta.tigris.org/> reduction of the original web page points to this JavaScript (opening this tag in an HTML file will reproduce the crash):

<script type="text/javascript" src="http://mysit.es/javascripts/codeeditors.js?v=1195518434"></script>

Note that I had to create my own "topformatflat" script:

#!/bin/sh
exec cat

My testit.sh script was:

#!/bin/sh

`/Volumes/WebKit/WebKit.app/Contents/MacOS/WebKit /tmp/delta/MySit.es.html`
STATUS=$?

echo ">>>>> $STATUS"

if [ $STATUS -eq 139 -o $STATUS -eq 138 ]; then
    exit 0;
fi

exit 1;

> `/Volumes/WebKit/WebKit.app/Contents/MacOS/WebKit /tmp/delta/MySit.es.html`

Used WebKit nightly r28007.

Loading this page under guard malloc triggers the following crash:

I'm waiting through another guardmalloc run to see whether fixing this regexp issue fixed the malloc errors.

Reduced test case (will crash ToT)

Another regular expression crasher.

I "inlined" the <script> tag and reran multidelta with the new source file.  It got the file down to 7 lines (including the script tags), but it was obvious that the regex was causing a crash at that point.
Comment 9 Mark Rowe (bdash) 2007-11-25 13:45:40 PST
I just need to build a layout test then I'll throw my fix up for review.
