[MacRuby-devel] Has the team given up on continuous integration?

Thanks Eloy. I'll take my panic pants off and get it at it again.

I feel somewhat sheepish since I have been trolling through this code for months (I think a year now) and haven't been able to submit a single patch. But I will continue to try.

Cheers,

And as Matt said, the String#dump failure is one that can't be helped right now, so you should consider this to be ‘green’. Or better yet, you could fix these.

When it was isolated failures, I felt Ok, but the the malloc exceptions and the like give me definite pause.
