      Steps to reproduce:

      There is no possibility to reproduce issue in a wild, but it can explain many "not reproducible" issues related to pdh
      The reason is in the code like: 

      elements.CounterName = uintptr(unsafe.Pointer(windows.StringToUTF16Ptr(counterName)))

      Result:

      GC does not track memory after uintptr and as a result in some cases we can use pointer to GC freed memory 

      Expected:
      Introduce intermediate variable and make refactoring similar places
