[fpc-devel] compiler bug?

[peter green]

I think the old saying goes garbage in garbage out.

range checking should probablly catch this sort of stuff but that has a high
performance penalty and is therefore usually disabled.

At the end of the day if you force out of range data into your booleans then
its your problem.
