Hello,

  ACE VERSION: 5.5.9

    HOST MACHINE and OPERATING SYSTEM:

    TARGET MACHINE and OPERATING SYSTEM, if different from HOST:
    COMPILER NAME AND VERSION (AND PATCHLEVEL): Microsoft Visual 
Studio.net (MSVC 7.1)

    THE $ACE_ROOT/ace/config.h FILE: config-win32.h

    THE $ACE_ROOT/include/makeinclude/platform_macros.GNU FILE [if you
    use a link to a platform-specific file, simply state which one
    (unless this isn't used in this case, e.g., with Microsoft Visual
    C++)]: N/A

    AREA/CLASS/EXAMPLE AFFECTED: N/A

    DOES THE PROBLEM AFFECT:
        COMPILATION? No
        LINKING? No
        EXECUTION? Yes
        OTHER (please specify)?

    SYNOPSIS:
        I used a combination of Qt and ACE in my application.
        I start the ACE proactor in a QThread, everything is just fine 
until the program exit.
        I end the proactor event loop, this has the effect of 
terminating the QThread.
        I wait the QThread termination.
        I call the ACE::fini() and the program is block here.

    DESCRIPTION:
         Here a structure of MyProactor class that is a QThread:
          MyProactor::run() ( QThread execution function )
          {
                ACE_Proactor::run_event_loop() ;
           }

          MyProactor::stop()
          {
                 ACE_Proactor *proactorInstance = ACE_Proactor::instance() ;

                // Check if the ACE Proactor instance pointer is valid
                if( proactorInstance != 0 )
                {
                    // Stop the ACE Proactor event loop
                    proactorInstance->proactor_end_event_loop() ;
                  }  
             }

          And my termination method

          Bootstrap::finalize()
          {
                   // Stop and wait my proactor execution
                  myProactor.stop();
                  myProactor.wait();

                   ACE::fini(); --> at this point the application is 
blocked.
           }
