I suspect since the method had no prototype the compiler just assumed
the default id return type, but due to a bug didn't generate a
warning. The problem is most likely the calling method was expecting
the return value to be an integer (id; pointer) but instead is a
float. Even with a cast being assumed the calling method is still
having a floating point register trashed by believing it was safe.

I'd have thought that in the case:
// id anonymous
float f = [anonymous position];
the compiler ought to assume that the method being used is the one
returning a float, or if not at least warn about an implicit cast from
CGPoint to float. Perhaps if it were -(int)position rather than
-(CGPoint)position, you might not expect a warning, but in that case
you would expect a cast, so it shouldn't break.
However, that does appear to be what is happening. In the absence of
any other explanation, I'd call it a compiler bug.
