Comment(by erikd):
I've been playing around with the various optimisation flags that GHC
provides and found that my current test fails with an optimisation of
`-O1` and passes with optimisation of `-O1 -fno-enable-rewrite-rules`
suggesting the problem is likely being triggered by PowerPC specific code
generation triggered by something the rewrite rules are doing.
I'm now looking at the various dump outputs.
