Attached is a patch that fixes a context reduction stack overflow in your dimensional package.

Thanks Bas, was the build failure on GHC 7.0.3? I don't believe this problem occurred on 7.0.1 and 7.0.2 although I'm not sure about the latter. I'm a little behind on GHC versions myself, waiting for 7.0.3 to get in the HP.

Yes, I'm using GHC-7.0.3

I noticed something weird though (that's why I'm CCing the ghc list). When I cabal build dimensional-0.8.2 I first get the context reduction stack overflow when I then build it again I get the error again (as expected). However when I try to build it for the third time it succeeds! Why is this?

I attached the build log.

It looks like the first two times it build all seven modules, failing on CGS, while the last time it decides to build only CGS. Strange indeed.

Anyway, I'll upload a patched dimensional to Hackage right now. But I'll need to figure out how to get my ssh key on code.haskell.org before I can push the patch to the repo...

Just mail your public key to support@community.haskell.org. Thanks, Bas
