Comment(by datenwolf):

 No, happy is not the first package built with the new compiler. In fact
 the happy build was part of a `haskell-updater --upgrade` run, and several
 (about 50 or so) other packages built just fine.

 What's even more interesting though (and why the Bug is probably better
 left with the gentoo-haskell folks) is, that if I use cabal-install to
 install happy into my user directory it builds just fine.

 I also have found two other packages affected in the same way:
 texmath-0.6.1.2 and pandoc-1.9.4.5

 In both cases `./setup` bails out with a strange closure type evacuation.
 But at least texmath can be installed through cabal-install just fine.
 pandoc doesn't install because the system package manager installed
 packages (bytestring to be specific) is in conflict with dependencies.
