GHC 7.2.1 rc1 crashes while compiling the text package

I'm doing a sweep over all of my packages with the first 7.2.1 release candidate, and the text package fails to build:

[24 of 38] Compiling Data.Text        ( Data/Text.hs, dist/build/Data/Text.o )
ghc: panic! (the 'impossible' happened)
  (GHC version 7.2.0.20110728 for i386-unknown-linux):
	cgLookupPanic (probably invalid Core; try -dcore-lint)
    $w$j{v s1Ju9} [lid]
    static binds for:
    local binds for:

This is easily reproduced with a simple cabal install text.
