Replying to [comment:6 igloo]:
> Oh, for some reason I thought that `-fregs-graph` was the default in
6.10, which was why it worked in the past. Is there a reason not to make
it the default?
Partly paranoia: the linear-scan allocator has had a good shakedown, it
only has two known bugs (this one and another one that doesn't actually
show up in practice), whereas `-fregs-graph` has hardly been tested in the
field. Partly performance: I believe `-fregs-graph` is slower, but we
haven't measured it systematically yet. We'll probably want `-fregs-
graph` to become the default in 6.12, however. I'm still considering
whether we want to keep the old allocator around too, perhaps for non-
optimised compilations.
