Tern+CodeMirror crashes Chrome

[dangoor]

I'm just filing this here in case others run into this problem. Tern should not be able to crash the browser, so this is really a bug in Chromium (and I've filed it there).

For me, this URL will reliably crash Chrome:

http://dangoor.github.io/tern/doc/demo.html?crash

That is the stock Tern demo, but with:

• two different JS files (polymer and web-animations)
• useWorker = true

I find that it also crashes even with useWorker = false, which you can see here:

http://dangoor.github.io/tern/doc/demo.html?crash&noworker

(If you remove the query string, you get the normal Tern demo, which works just fine).

@marijnh: feel free to close this or keep it open for tracking until the bug is fixed in Chromium. Right now it says it's restricted, but the bug is 260811.

One more note: I believe (or rather, hope) that this is the same crash we're seeing in Brackets.

@dangoor I tried this in Chromium 51.0.2704.79 in Ubuntu 16.04 (64-bit) and neither URL was able to crash Chromium.

Possibly this is resolved? The bug is still restricted.

@aikeru Yes, the Chromium bug is fixed. Thanks for bringing this back up!
