Description Joe Strzemp 2011-10-10 15:35:22 PDT

After loading up page:
http://sanfrancisco.cbslocal.com/show/the-daily-madden/#listen-live

Try listening by clicking on "Listen LIVE" icon/link on the near upper right side of the page.
This work on r97026 and fails on r97032.

The console on r97032 reports:

    TypeError: 'undefined' is not a function (evaluating 'c[l](0)')

It seems that Changeset r97030 is a likely candidate for this regression.

Experience on:
Mac 10.6.8
Webkit: Version 5.1 (6534.50, r97032)

Comment 1 Joe Strzemp 2011-10-11 18:12:16 PDT

Bug still exists in r97166.

Comment 2 Joe Strzemp 2011-10-30 14:00:25 PDT

Later bugreport 70094 (and fix) seems to address the problem
caused by r97030:
"DFG should not always speculate that a ByVal access has an integer index"

The problem reported by this bugreport is fixed as of nightly build r98825.
