Isn't this the same as #8748? If so, it's already fixed in RC2. No it isn't. I'm at commit 8a2989c5df76712d5cd52ff918d4e6c1a741a90b and I managed to bootstrap RC2 up to that commit.
This ticket is about self-bootstrapping using RC2 which I did for openSUSE's ghc so far. IIRC a selfbootstrapped ghc is required because of ABI changes between releases. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8820#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Selfbootstrap, however, fails now at a later step. I will close this ticket and file a new ticket against RC2. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8820#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
