Description
MoveAndUpdateClosure::do_addr calls calc_new_pointer in an assert, but that function has side effects. It calls PsParallelCompact::fill_blocks on the region containing the address and marks that region filled. This appears to be "harmless" in the sense that this is permitted to occur multiple times for a region. But this could have the effect of masking lack of region filling somewhere else for release builds.
