OMP critical section causes hang in Simulator when stacks placed in cached DDR3

When running OMP executables in the simulator with the following configuration:

var stackRegionId = SharedRegion.numEntries
SharedRegion.numEntries = stackRegionId + 1;
SharedRegion.setEntryMeta( stackRegionId,
                            {   base: 0x89000000,
                                len:  0x0100000,
                                ownerProcId: 0,
                                cacheEnable: true,
                                createHeap: true,
                                isValid: true,
                                name: "stack-ddr3-cached",
                            }

);

OpenMP.stackRegionId = stackRegionId;
OpenMP.stackSize = 32768;
