 This is a semi-reproducible error that shows up in the test suite for
 http://hackage.haskell.org/package/htsn-import.

 You have to run the test suite a few times, but it does crash regularly.
 Steps to reproduce:

 {{{
 $ ghc --make -O2 -o setup Setup.hs
 $ ./setup configure --user --enable-tests
 $ ./setup build
 $ ./setup test testsuite
 }}}

 If that doesn't crash, `./setup test testsuite` can be re-run until it
 does. Sample crash:

 {{{
