Using a 32bit Nightly hourly after Ion landed. Cset: fdfaef738a00 Go to the pdf.js web demo (see URL field) and start zooming in and out of the example PDF using the reader's toolbar buttons. After some 10-20 zoom changes the browser crashes.

Note that this is being mentioned in bug 790663, possibly a way to repro this crash.
Easier way to reproduce. 1. Go to http://html5puzzle.appspot.com/ 2. Click Play. 3. Wait a few seconds. bp-9896c159-57e9-4987-9645-9e4e32120912 bp-a0805bca-95ae-4824-968c-ab5402120912 bp-fb70d73d-7238-4400-a3be-e0fa22120912 bp-2b9668e2-fa0c-40e1-a466-590442120912 bp-5037ac3d-7734-4cbd-9fdc-7726c2120912 bp-9bd3ef68-dc11-4a00-bf7c-a3c6e2120912
I get this in the profiler addon as well.
There are about 400 crashes per build.
Created attachment 661713 [details] Windbg Log File http://seb.ly/demos/MMOsteroids.html causes Nightly to crash. https://crash-stats.mozilla.com/report/index/bp-ad8cf2a6-2173-4333-96b9-bc1232120917 https://crash-stats.mozilla.com/report/index/bp-675f4733-65e6-45bf-bfe6-39c9d2120917 Probably not necessary at this point, but I'm attaching a windbg log anyways.
Changing the URL has this one is an immediate crash.
I can reproduce this, it's a regalloc problem with LSetDomProperty. JSRope::flattenInternal is just one of the many places this will crash, so fixing it should hopefully also get rid of some other new topcrashes. With bug 779411 this would have asserted immediately, will rebase and land that ASAP.

Are you sure you were using a nightly build and not an hourly?
Hm, you're right that the nightly doesn't include that. I am using a nightly build, and as of today it no longer reproduces for me. I'll leave open for someone else to confirm tomorrow.

I'm trying the latest Nightly and it doesn't crash anymore with the links posted previously. So I guess it's fixed.

I'm still crashing on http://www.syngames.net/game/braidjump on the latest nightly.

Whoops, I thought bug 791589 was a dupe of this - sorry.
