See Bug 835712, comment 4. The second patch in that bug (also linked here in URL) causes this try burn:

What's disturbing is that when I built it locally, it failed initially, but after a few edits and weak attempts at workarounds, it suddenly built fine. I removed my workaround attempts and it still built fine. I rebuilt it on inbound as opposed to central where I had it and it still built fine. It was only when I did a try that it failed.

I suspect it sometimes generates in the correct order and sometimes in the wrong order, which makes it easy to burn the tree by mistake.

The relevant part of that log:

  In file included from
  ../dist/include/mozilla/dom/RTCConfigurationBinding.h:31:23: error:
    use of undeclared identifier 'RTCIceServer'
  Optional< Sequence< RTCIceServer > > mIceServers;
  ../dist/include/mozilla/dom/RTCConfigurationBinding.h:31:38: error:
    expected a type
  Optional< Sequence< RTCIceServer > > mIceServers;
2 errors generated.

The relevant part of dom/webidl/RTCConfiguration.webidl:

  dictionary RTCIceServer {
      DOMString  url;
      DOMString? credential = null;

  dictionary RTCConfiguration {
      sequence<RTCIceServer> iceServers;
Looks like something I forgot to handle in bug 790975.

And you're right that the ordering is currently semi-random: there's a Python set() involved.  :(

Jan-Ivar, does that patch help?

I was hoping to land my constraints patch, bug 835370, before Tuesday but it is blocked by this. Any chance of it landing soon?
Needs review from Peter.  With any luck, that'll happen Monday; if so feel free to push this with your patch if I haven't gotten to it first!
