#4338: weird discrepancies between TFs and FDs in GHC7

Architecture: x86 | Failure: Compile-time crash
--------------------------+-------------------------------------------------
Comment(by illissius):
I did a clean build from HEAD. Bar.hs still builds correctly; Foo.hs now
results in a panic irrespective of which type signatures I supply or omit:
{{{
$ ghc Foo.hs
[1 of 1] Compiling Main ( Foo.hs, Foo.o )
ghc: panic! (the 'impossible' happened)
(GHC version 7.1.20101008 for i386-unknown-linux):
topEvBindPairs $dFoo{v agj} [lid]
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
}}}
