Pierre and I have been working (privately) to solve the exim problem that I mentioned in the following post: http://cygwin.com/ml/cygwin-developers/2003-02/msg00125.html It appears that under certain conditions Winsock's closesocket() is not happy closing a socket more than once. See the attached test case, sc9.cc, which demonstrates the problem when run under LocalSystem: $ sc9 close(fd2) failed with 108 Note that the problem follows the second close(). If I switch the order of the close() calls, then dup()-ed socket closes without any errors. Hence, I don't believe that this problem is directly related to dup(). I have worked around the problem with the attached patch to fhandler_socket::close(). Is this a reasonable way to solve this problem? Or, does anyone have any other suggestions? BTW, this is YA problem that goes away under strace and gdb, which make debugging this problem difficult. Sigh...
