ClementBera uploaded a new version of VMMaker to project VM Maker:

Ancestors: VMMaker.oscog-eem.1926

Now that the trampoline for context inst var store can be called on single contexts, we need to update the trampoline to work with single contexts

Item was changed:

  	<api>
  	"genStorePop:MaybeContextReceiverVariable: filters out unmarried contexts
  	 but not arbitrary objects in subclasses.  It answers maybeMarriedContext so
  	 that the StackToRegisterMappingCogit can keep ReceiverResultReg live."
