My IB Gateway version is latest stable 10.30.1t, API version is latest stable 10.30.01 running on Windows. I replicated this on the sample TestCppClientStatic (debug, both win32 and x64). 1) start IB gateway, 2) start TestCppClientStatic, 3) shutdown IB gateway, 4) the program hangs. After putting a breakpoint at m_pEReader->stop() in void EClientSocket::eDisconnect(bool resetState), it seems the hang happened at WaitForSingleObject in EReader::stop(). See call stack below.

--hang here --> WaitForSingleObject(m_hReadThread, INFINITE);
