Has anyone run into problems with %f on 64-bit targets?
With large numbers passed in to %f, it appears xdtoa
overruns s in floatfmt. Has anyone already fixed this?

I haven't run much fp on the amd64 as yet, only enough
to verify it works via astro. If you can give me an example
I can put it on the list of things to check and fix.

was that on Plan 9 or plan 9 ports (and if so, which platform)?

As Jim discovered, it isn't 64-bit specific.
With %f, the stack-allocated buffer s in
floatfmt isn't big enough and so with a large
argument, the buffer gets overrun.
