Building ghc with the following build.mk:
{{{
BuildFlavour = validate
ifneq "$(BuildFlavour)" ""
include mk/flavours/$(BuildFlavour).mk
endif
GhcLibHcOpts += -g3
GhcRtsHcOpts += -g3
GhcStage2Opts += -g3
}}}
gives

This is specifically a duplicate of #14122, which is one of piece of the mess that is #14123. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14406#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
