Thanks for keeping an eye on this one, Eric... As I said in the original
report, it seems to be very sensitive to many things --- my gut feeling is that
switching to gcc-3.3.1 'fixes' the problem in the same way that removing a few
lines from the function 'fixes' the problem... The optimizer bug is still
there, just not showing up under these conditions any more...
Let me know if there's anything else I can do to help...
