Test failure in 0.9.0.9

[hololeap]

I found a test failure in 0.9.0.9, being built in Gentoo. This gist is a copy of the build log, which includes the test failure (highlighted).

The failure is in Parser.parseSong parses songs and it failed on its 93rd round, so it seems like this is a bit of a corner case. I hope reporting it helps.

The same failure occurs building on guix: http://ci.guix.gnu.org/log/4afh942h5ys60hixrnpfc8va7sjskmxd-ghc-libmpd-0.9.0.9
