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 ?
Cheers,
- Mgix
