Hi,

Using latest sip/PyQt snapshots with Qt4.4, see following:

>>> from PyQt4.QtNetwork import QHostAddress, QUdpSocket
>>> socket = QUdpSocket()
>>> success = socket.bind(QHostAddress("0.0.0.0"), 5555)
>>> success
True
>>> socket.readData(-1)
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

Simply returning None when a negative size is given is a better idea.

Regards,
