Hmmmm, how come you consider this an instance of #11303 and not #11276?
Mostly guessed so, because #11276 talks about exponential time, rather than exponential memory usage :-) Do you need me to provide you a smaller testcase? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11303#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
