Yes, it appears to have been a corrupted 'hi' file. cleaning everything out and starting from scratch fixed it. I was seeing it on both compilers because my two systems are synchronized via unison so the bad file got bounced back and forth.
I have not tried using 7.2 yet, the separation of haskell98 and base is a huge pain for a lot of my projects, I have not decided on an appropriate workaround yet so I still target 7.0 and 6.12 (the releases that came with the last two versions of ubuntu by no coincidence) John _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
