Comment(by simonmar):
I wasn't able to reproduce it with `bug.hs` either. '''However''', I have
instrumented the RTS with calls to check the FPU stack all over the place,
and one of them randomly triggers in my stage2 compiler while compiling
hmatrix. So there is definitely something wrong, but whether I can catch
it happening is another matter.
