[Mono-dev] SIGSEV Cores on Solaris

[Aaron Clauson]

Hi,

I forgot to say it was attempting to bind to the reserved port on a separate
thread. If the bind is attempted on the main thread then the exception is caught
ok.

This code throws a SIGSEGV on Solaris for me.

In main:
IPAddress m_testIPAddress =
Dns.Resolve(Dns.GetHostName()).AddressList[0].Address
Thread testIPAddressThread = new Thread(new ThreadStart(TestIPAddress));
testIPAddressThread.Start();


private static void TestIPAddress()
{
 try
 {
   IPAddress testAddress = m_currentTestAddress;
   Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream,
ProtocolType.Tcp);
   socket.Bind(new IPEndPoint(testAddress, 80));
 }
 Catch(Exception excp)
 {
  Console.WriteLine(excp.Message);
 }
}

Thanks,

Aaron
