The Squeak Spur VMs will now run Pharo images that have been bootstrapped (SpurBootstrap bootstrapPharoImage: 'myimage'), but be aware that the bootstrap does not yet update the modified packages in a Pharo 4 image, and hence sources for the modified methods is unavailable.

CogVM binaries as per VMMaker.oscog-eem.812/r3039

Spur: Fix bug in old space GC processing of weaklings. Old code didn't trace strong references in weaklings to weaklings in markWeaklingsAndMarkAndFireEphemerons. Make sure nilUnmarkedWeaklingSlotsIn: can be inlined. Bug shows up as crashes in Pharo Spur, Pharo making much more use of weakness than Squeak or Newspeak.

Fix bug in nilUnmarkedWeaklingSlotsIn: which was not guarding the isForwarded: check with an isFreeObject: not check.

Move the scanning for young references in scavenger processing of weaklings into processWeakSurvivor:.

Fix minor slips in allObjects & allInstancesOf: which should only empty weaklingStack if marking.

Fix a couple of storePointer:ofObject:'s being applied to objStacks.

Rename isReallyForwarded: to isUnambiguouslyForwarder: and add an assert to isForwarded: to catch accidental applications to free objects.

Fix longPrintOop: for free referents.

V3 Cogit: Fix bogus assert fail due to signedness.

Slang: Assign complex expressions to loop variables in value: expansions. Old code would replace variable with expansion of actual parameter everywhere. -- best, Eliot
