I noticed this occurs after the commit:

    Cygwin: pty, console: Fix handle leak which occurs on exec() error.

    - This patch fixes the handle leak which occurs when exec() fails
      with an error. The duplicated handles will be closed when the
      exec'ed process is terminated. However, if exec() fails, the code
      path does not reach to the code closing the duplicated handles.
      To implement this fix more appropriately, the setup, cleanup and
      closing pty codes which was previously located in are
      encapsulated into the fhandler_pty_slave class functions.

Now, I am looking into this problem. Please wait a while.
