In some earlier upheaval I introduced a bug in the ambiguity check for genreric-default method. This patch fixes it. But in fixing it I realised that the sourc-location of any such error message was bogus, so I fixed that too, which involved a slightly wider change; see the comments with TcMethInfo. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7497#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
