Obscure warning: Var/Type length mismatch when using GADTs and TypeFamilies
GHC 7.4.2 and 7.6.1 both write obscure warning without any link to source line:
$ ghc --make test.hs
[1 of 1] Compiling Main ( test.hs, test.o )
Var/Type length mismatch:
[]
[main:Main.Credit{tc ra2}]
Var/Type length mismatch:

Near to minimal example (my real program is quite big and uses GHC type system a lot): http://hpaste.org/78958
GHC 7.4.2 output: http://hpaste.org/78959
GHC 7.6.1 output: http://hpaste.org/78961
