Did you try to
- look if you get the expected file descriptor from dup?
- look which errno you get?
- run the application under strace?
- run the application under gdb?
After that and if you found that the problem is actually a Cygwin
problem, please write a *short* testcase which allows to reproduce
the problem and I';ll be happy to have a look into this issue.
