Hello Henning, Brent Do you think you could advance this bug by coming up with a smaller example? I wish I could do it but I think I would be pretty slow at that. Sorry. It would be good if others could see if they can compile numeric-prelude using 7.10.2 on other platforms, i.e. it would be good to know if this bug is specific to the Mac platform.

Comment (by George):

Sorry, I don't think I can, I will however send mail to the package maintainer, Henning Thielemann and cc Brent Yorgey whose species package depends on numeric prelude. I set the priority as high as it seems that shipping a release that can't compile a package it could previously is not a good thing. The impact of the bug is not clear. However, I personally don't need this fix.
