Confirmed with r31072.  Didn't actually get CNN to crash for me, but lynda.com (bug 17861) did.

Just confirming that I had about 4 or 5 similar crashes yesterday from some random sites. One of which I can remember was after doing a function search on php.net.

r31055 crash log

I've seen the same issue on several sites with r31055. Crash log attached.

Might this be the cause?

Incase anyone is having trouble reproducing this bug, well if you have a .mac account login at http://webmail.mac.com/ and it will crash within a second (which BTW, is very very annoying)

[Antti Koivisto]

Likely to be duplicate of memory smasher Bug 17862.

[Antti Koivisto]

Yep, the patch there fixes webmail.mac.com crash too.
