PVS-Studio warning V519 for wxWidgets

WCHAR szEntryName[ RAS_MaxEntryName + 1 ];
WCHAR szPhoneNumber[ RAS_MaxPhoneNumber + 1 ];
WCHAR szCallbackNumber[ RAS_MaxCallbackNumber + 1 ];

bool wxDialUpManagerMSW::Dial(const wxString& nameOfISP,
                              const wxString& username,
                              const wxString& password,
                              bool async)
{
  ...
  // default values for other fields
  rasDialParams.szPhoneNumber[0] = '\0';
  rasDialParams.szCallbackNumber[0] = '\0';
  rasDialParams.szCallbackNumber[0] = '\0';
  ...
}

Most likely this is what should be written here: rasDialParams.szEntryName[0] = '\0';

This suspicious code was found in wxWidgets project by PVS-Studio static code analyzer.
Warning message is:
V519 The 'rasDialParams.szCallbackNumber[0]' variable is assigned values twice successively. Perhaps this is a mistake. Check lines: 832, 833. core dialup.cpp 833
