[Vm-dev] [SPUR] ImageSegment>>#restoreEndianess works head-ful but
not head-less, why?

Dear all,
the current Squeak Trunk on Spur is crashing with a 'Recursive not understood error encountered'
in ImageSegment>restoreEndianness. (See http://build.squeak.org/job/SqueakTrunkOnSpur/608/console)
However, running this thing not headless as jenkins but headful, the indicated test does not crash there.
The only thing I noticed is that restoreEndianess relies on the total temporal order of objects:
object := segment.
[object := object nextObject. "all the way to the end of memory to catch remade objects"
object == endMarker ifTrue: [inSeg := false]. "off end"
" .... "
object == 0] whileFalse.
I cannot understand where a recursive dNU should appear here or why it should work
with X but not without.
I am truly puzzled.
I know that ImageSegments are a tad tied to the V3 Memory layout, but nevertheless, I think
spur shouldn't choke that hard on them…
Best regards
-Tobias
