FYI, ipc-daemon2 is now obsolete, and unless you have an unofficial
package that depends on it, I suggest you stop it, as it's only wasting
system resources.

Not nearly enough information, the problem reporting guidelines at
<http://cygwin.com/problems.html> were not followed (e.g., no attached
cygcheck output), and your code snippet isn't self-contained, doesn't
compile (even discounting Yahoo's line wrapping -- next time, please
attach the code), and doesn't reproduce the bug. In the absense of the
facts, I can only offer a WAG: does $CYGWIN contain "server" when you run
your program?
