My assertions in bug 531460 (which I really need to land soon!) caught a bug introduced by the patch from bug 500328. This was while running the mochitests in dom/tests/mochitest/whatwg. This appears to be trunk-only (I think?), but marking security-sensitive for now.

I confirmed that the 1.9.2 branch is unaffected; an MXR search for "nsAutoGCRoot(" turned up only this problem on mozilla-central and no problems on mozilla1.9.2. We should probably clear the core-security flag when we ship the next trunk alpha.
status1.9.2: --- → unaffected
