7.10.1RC2 compile problem? ghc: internal error: PAP object entered!
Maybe this is something I shouldn't be doing, but I thought it was worth mentioning in case I have found a compiler bug. Should I file a bug for this? cabal install *--allow-newer=base* accelerate ...

(GHC version 7.10.0.20150123 for x86_64_apple_darwin) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug I suspect this has to do with `--allow-newer=base` allowing template-haskell-2.9.0.0 to be re-installed (which then becomes a build-dependency of `fclabels`). GHC 7.10, however, comes with template-haskell-2.10.0.0 e.g. try the following in an empty sandbox: cabal install fclabels --allow-newer=base --constraint 'template-haskell == 2.9.*' (wheares a plain `cabal install fclabels` in a fresh sandbox should succeed w/o panics with GHC 7.10) ___ ghc-devs mailing list ghc-devs@haskell.org http://www.haskell.org/mailman/listinfo/ghc-devs

I didn't encounter this when I tried to reproduce the issue because I have a bunch of lines like constraint: template-haskell installed in my .cabal/config file.
