Beta, Aurora fail to load the page. 

XP aborts with an unrelated abort. Linux fails to load the page.

Opt build fails to load the page.

bob, is there a proxy involved?

Comment 2

[Patrick McManus [:mcmanus]]

I can't get a stack or abort out of this test case - even using a debug os x nightly from 3/26 which would seem to be about right. I just get a failure to load the page, which is expected. I'll try windows next just to be thorough.

Even if there isn't a proxy involved, I think the patch from 741056 would address this stack trace. Bob, can you test the try build linked below and report on that?

I can't resolve the host any more.

Ah - I couldn't either. I thought that's what you meant by page fails to load.

Given that fact, and the fact that the stack touches the same code as the patch for 741056 I'm going to mark this a dup as the most likely disposition...let me know if that doesn't make sense to you.
