This is caused by missing freeing the heads of DepGraph in IQ. IQ only clears out the heads when instructions reach writeback stage. If a instruction is squashed before writeback stage, its head of dependency graph, which holds the instruction's DynInstPtr, would not be cleared out. This prevents freeing the DynInst of the squahsed instruction even after it is committed.
