michael, yes, these are a bug that snuck in POST RC2, its getting fixed this week. Contact Austin and ask for a binary, or build from 7.8 tip 



I just woke up, came downstairs, and kicked off a GHC build. If anyone has a Linux 64-bit binary ready and can send me the link, I'll be able to test that much sooner.

Someone has also reported a second bug, which may or may not be fixed by the proposed 7.8.2[1]. Hopefully I'll have more information in the next few hours.

Well.. that's pretty ick.
M. Snoyberg - when you say "broken a number of my packages", do you mean the Yesod suite?

Let's see how GHC central decides to handle this... if it is a quick turn with just this fix, then we'll be able to move to 7.8.2 quickly. If not, then depending on what packages are broken with it, we'll need to decide the next course of action.

I've gotten reports on three or four different packages so far. But the problem is that I'm now getting reports of build failures on packages that seemed to succeed when I first tested, so I don't know exactly what's going on. Note that these are regressions since rc2.

What I'd really like to do is get the candidate release build and run a stackage build with it to see if there are any other regressions.
