Can you also add a test for the references provided via SetReferenceFromGroup
call from a one-object group to make sure heap profiler will handle it properly?

[marja, 2013/04/24 14:33:53]

Offline discussion: references from an one-object object group are converted
into the same format than references from an object.
test-global-handles/ImplicitReferences tests this. So from the heap profiler
point of view, it shouldn't make a difference. However, I made one of these
references to be from an one-object object group.
