Internal compiler error on haskell-src-exts 1.14.01 (profiling)

I'm configuring and building haskell-src-exts like this:

runhaskell Setup configure -O -p  --enable-shared \
        -fbase4
runhaskell Setup build

It builds the ordinary bits just fine, but when it gets to compiling for profiling:

[ 1 of 22] Compiling Language.Haskell.Exts.Annotated.Syntax ( src/Language/Haskell/Exts/Annotated/Syntax.hs, dist/build/Language/Haskell/Exts/Annotated/Syntax.p_o )
