@pnkfelix By "Backtrace for issue-868.rs" do you mean for issue-9047.rs?

[lkuper]

I had the same three failures on Linux.

@lkuper

By "Backtrace for issue-868.rs" do you mean for issue-9047.rs?

my mistake, will fix.

[pnkfelix]

@lkuper by the way, I think the workaround in #9129 is probably applicable to all three of these cases (all of which are uses of break 'label or loop 'label, I believe.

[lkuper]

Can reproduce on OS X too, against 150b4ff. (gist)
