I've crashed several times today in my normal profile, normally I almost never crash. I didn't have a problem with the 2011-09-18 nightly. The 2011-09-20 has the crashes (I'm unsure about 2011-09-19, I may have skipped it, I don't remember).
I seem to be able to reproduce eventually by going to http://www.flickr.com/photos/lucasrocha/sets/72157627529094579/ and then ctrl-clicking on each image to open in a new tab.
I reproduced in a opt build with debug enabled (rev b15856d4b114) and got this stack:

I've also crashed without loading a bazillion tabs with images. (I'm 64bit, so I don't think I'm hitting OOM.)
Brian, if I had a guess, the new getter IC is missing a verifyRange change in the linker.

Yes, this is the problem. The getter IC only verified range against the JITScript's code, and not the previous PIC stub.
