Thanks. I got enough info to reproduce the problem. It looks like a case of bad optimizer applied by the compiler when (safety 0) is used.

So, as a quick fix, if you have direct control over this you could raise the "safety" level to 1 or more (anything above 0) and the problem should disappear.

I will investigate some more and fix the guilty optimizer shortly.
