Marc replied:
Looking at the code, it seems to originate from the
native method close0() called from
org.eclipse.cdt.utils.pty.PTYInputStream.close().  My only thought is that
maybe there is a threading issue and the same PTY stream is closed twice at the
same time: the first time by the Debug Platform which is monitoring the stream
(OutputStreamMonitor) and in a separate thread in MIInferiorProcess.

I'm not sure how mutli-threads are handled with the Debug Platform.  Maybe we
can discuss.
