I've fixed these crashes. Some slightly delicate footwork around let-floating.
Please watch out in case I've done something that worsens performance; I don't

Argubly rewrite rules should not fire with -O0, and it turns
out that when compiling GHC.Base with -O0 we get a crash if

Brilliant.
I've just successfully installed it and run it. Seemed great.
As well as adding the binary to my path, it also added

* FIX Trac #1332: make isStringTy work right
For some ancient reason, TcType.isStringTy was treating newtypes as
transparent, which is quite consistent with isIntTy, isBoolTy etc.
(I think the reason is that isStringTy was written to go

Are you sure you compiled both with the same flags (e.g. -O)?
Maybe doing -ddump-simpl and looking at the code for selectProofBasis (where
most of the time goes) would be illuminating.
If you can't narrow it down any more, then I
