	- same game again, broken 5.10 finds yet another assertion
          failure, and the workaround causes additional runtime warnings.
          Work around the next assertion AND the warning. 5.10 seriously
          needs to adjust it's attitude against working code.

	- you work around one -DDEBUGGING assertion bug in perl 5.10
          just to hit the next one. work around this one, too.
