Ok. Have you actually encountered this problem, or is it
hypothetical?
Upthread, you were talking about the problem of supporting both C99
and C11. The example we're now discussing doesn't seem relevant
to that. You were also making some point about which component
(compiler, run-time library, OS?) should be responsible for the
behavior of printf. The only relevant issue I can see is that it
affects whom you should complain to if something doesn't work the way
you expect -- that, and the possibility that you migth not be able to
switch to an implementation that's to you're liking quite as easily.
I'd say all of this is outside the scope of what the C standard
can reasonably specify.

I suspect that emulating the behavior of sprintf at compile time
for optimization purposes probably isn't worth the effort. As far
as I can see, such an optimization would be useful only for code
specifically like yours, and I just don't see it being common enough
to be worthwhile.
And if different sprintf implementations actually do vary in their
behavior, then a compiler *can't* do that kind of optimization
(unless it can assume that it will always be used with a library
that behaves in a particular way).
If you're arguing that the output generated by printf for
floating-point values should be consistent across implementations,
that's a reasonable argument -- though it's complicated by the fact
that different systems can still have different floating-point
representations. IEEE hasn't *quite* conquered the world yet.
