We use "MemoryIsNotDeallocated" to aovid internal expected leak reported
in Windows _Crt report, like:

    {
    #ifdef _MSC_VER
    	MemoryIsNotDeallocated memory_is_not_deeallocated;
    #endif

    	static ThreadIdToThreadLocals* map = new
	ThreadIdToThreadLocals();
	return map;
    }

But int the above code, only "new ThreadIdToThreadLocals()" is
protected, if we invoke "insert()" function of the return value,
the memory allocated in "insert()" will be reported to _Crt report
also. This change try to fix this issue.
