------- Comment #1 from bugzilla at digitalmars.com  2007-02-02 03:31 -------
The problem here is that 2.2 is not representable exactly. Constant folding
happens in different ways depending on if the optimizer is run or not,
resulting in slightly different answers due to roundoff error. Generally
speaking, an algorithm that depends on this is always going to have trouble.

To make the example work, use a constant that is exactly representable, like
1.25 and 2.25.

Not a compiler bug.
