Is this a known bug?

Well, it's not really a bug as all detection of loops is a bonus, if the optimizer comes across something of exactly 'x = x' it will replace it with error "<<loop>>" but not all loops optimize to that form.

Blowing the stack is not a bug?

Ah! are you saying 'jhc' blows its stack or the compiled program does? sorry, I misunderstood. yeah, that is a bug then. I have actually run into a few programs that blow stack, perhaps this is the cause. John -- John Meacham - ⑆repetae.net⑆john⑈
