[Vm-dev] Spur corrupts large images when saving

[Eliot Miranda]

Hi Yuriy,

    what's the version info in that VM?  I expect this is the same bug I fixed in

CogVM binaries as per VMMaker.oscog-eem.1679/r3602
 ...
Fix start up of images containing >= 16 segments.  The old code assumed
numSegments < 16 and failed to grow the segment records, resulting in objects
in segments greater than 15 to not be swizzled, and a resulting crash.
