It looks like libgmon's _monstartup() is called twice, which is > expected, but both times in the parent's process, which is not expected. I'm not set up to test this locally. Can you please check the *Windows* PID as well in your note function? There's a chance this is a false positive. Dependent on when the constructors are called, the Cygwin PID might not be set yet in the child.
