I would like to report what I suspect is a bug in Cygwin. Symptoms: . A DLL loaded with dlopen gets loaded twice . Cygwin freezes when exit() is called. This occurs in the following specific conditions: 1. All code is C++ 2. Main app is linked with a dll 3. Said dll has a static C++ object whose constructor loads yet another dll with dlopen. 4. dynloaded DLL also has a static C++ object whose constructor does a printf First, when the app launches, you notice that the printf statement in the constructor of the static C++ object in the dynloaded DLL is triggered twice. Second, when the app calls exit, it freezes. I have made a small tarball isolating the bug. It can be downloaded from here: http://www.mgix.com/cygfreeze.tar.gz I looked at the FAQ and the mailing list archive, but couldn't find a reference to this problem. Is this a known issue ?
