Status: UNCONFIRMED

(Toolkit :: Async Tooling, defect)

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20141115160330

Steps to reproduce:

See the attached test file.

yielding a generator should be the same as yielding a generator wrapped in a Task.spawn. But it isn't. This causes hidden errors in tests (?).


Actual results:

Test passes.


Expected results:

Test should fail.

The reason I expect those two to work the same is hg.mozilla.org/mozilla-central/file/cef590a6f946/toolkit/modules/Task.jsm#l73.
