The problem happens because we are not as careful as we should be
to "clear" Eden following a resize to expand into the survivor spaces,
which might have memory that was not mangled with the expected pattern.
This is a debug build only bug and does not in and of itself
indicate any problem in the product.
The bug goes back from Mustan all the way back to Mantis
(and perhaps earlier, but I didn't bother to check).

CMS needs to make sure it plays well with these options which are
useful for debugging.
