UPnPBase.cpp: In constructor ‘CUPnPControlPoint::CUPnPControlPoint(short unsigned int)’:
UPnPBase.cpp:880:1: error: jump to label ‘error’ [-fpermissive]
 error:

UPnPBase.cpp:832:8: note:   from here
   goto error;
        ^~~~~
UPnPBase.cpp:835:8: note:   crosses initialization of ‘char* ipAddress’
  char *ipAddress = UpnpGetServerIpAddress();
        ^~~~~~~~~
UPnPBase.cpp:834:17: note:   crosses initialization of ‘short unsigned int port’
  unsigned short port = UpnpGetServerPort();
