--- Comment #5 from digitman digitman63@gmail.com --- My scenario is typical for the work of the Embarcadero Rad Studio PAServer remote debugger - in a remote debugging session of a Win32 application, it launches two RmtDbgXXX.exe processes sequentially, the first process creates a listening socket, accepts an incoming TCP connection and passes the TCP socket to the second process to implement exchange with PAClient as part of the client part of the distributed debugger.
Due to this issue, remote debugging sessions are fundamentally impossible in any version of Wine.
