Description Moxiecode Systems 2011-03-02 15:26:07 PST 
Description:
Regexp doesn't return correct value on latest nightly and nightly builds after r72493.

Steps to reproduce:

1. Open the attached URL: http://tinymce.moxiecode.com/safari/regexp.html
2. Click the test link.
3. Observe that it's failing.
4. Observe that it doesn't fail on nightly builds before r72493.

Expected result:
The regexp should return the correct value as other browsers do and builds before r72493.

Actual result:
It's returning null so there seems to be an issue with back references.

Is this a duplicate of the bug 54978?
Comment 2 Alexey Proskuryakov 2011-03-02 19:52:52 PST 
It is, but it is also exactly the same as bug 55520.
