BCOs can only have 64k instructions: linkBCO: >= 64k insns in BCO

Fredrick Eaton (frederik@a5.repetae.net) said:

Here I'm reading a very large matrix from a file and turning it into a template Haskell expression. Probably not the most efficient thing to do, but the error message could be clearer...

*Main> let y = $(qFast (\f -> runIO $ readMatrixFile "data.txt" (runQ.f)));
ghc-6.4.2: panic! (the `impossible' happened, GHC version 6.4.2):
        linkBCO: >= 64k insns in BCO

Indeed, the error message is unhelpful.
