The oHandlers is not an array. It is a dictionary implemented using
std::map tree with std::string as key. This is perfectly valid construction.

Try to ensure the following in your own code:

int refCnt = dataSrc->GetSummaryRefCount();
if (refCnt > 0)
{
    dataSrc->Release();
}

assert( 0 == dataSrc->GetSummaryRefCount()); // <--- HERE
