   loads lots of SFW car images.

2.
ASSERTION: JS failed without setting an exception!: 'JS_IsExceptionPending(cx)'

3.
Assertion failure: compartment()->activeInference, at c:/work/mozilla/builds/nightly/mozilla/js/src/jsinfer.cpp:2125

All branches, Windows only. This can oom crash in a number of ways and you may need to repeat several times to get the assertion but it is pretty reproducible on a Windows XP box w/1G and Windows 7 w/2G. If you are running a 64bit build with lots of memory you probably won't see it.

If you need access to a test machine and have mpt access contact me for details.

This is essentially fall out from an image-suck crash

(We're using a new whiteboard tag.) Is this an OOM, or is something else going on?

It can be OOM if it doesn't assert first. I see a number of different js assertions under high memory pressure especially with these kinds of image suck oom situations. This one appears to be fairly reproducible on my test machines. Instead of js-triage-needed, I should just use the [js:investigate] and leave the priority to you, right?

Oops, I should have said something about how we're actually using the new tags. You can just leave it blank. As long as there isn't a js: in the whiteboard, Naveed or I will take a look at it and add something. We'll put js:investigate if we can't figure it out right away.
