Unfortunately, that's how it is. This is why your tests are so important.

I see. You seem not to be hitting any execution error, so that's secondary.

You probably are, not intentionally. Some of your compilation options
demanded VFPv3, so it should generate some of it (at least a few
VMOVs). Again, that's secondary.
