 While building yesod-based project for ARM architecture I have faced with
 error:
 {{{
 ghc: panic! (the 'impossibel' happened)
   (GHC version 8.0.1 for arm-unknown-linux):
     fint_tycon
   Block
   []
 }}}

 My yesod packages (inside cabal-sandbox on path `.cabal-sandbox/lib/arm-
 linux-ghc-8.0.1`):
 * yesod-1.4.3
 * yesod-auth-1.4.13.5
 * yesod-core-1.4.25
 * yesod-form-1.4.8
 * yesod-newsfeed-1.6.4
 * yesod-persistent-1.4.0.6
 * yesod-static-1.5.0.5

 My building machine is `Debian 4.7.8-1`.
