This dejagnu restriction was removed in 2016.  Try using a newer dejagnu 
release.

         * lib/remote.exp (standard_wait): Append any trailing characters
         to $output that may be still in $expect_out(buffer) when eof is
         matched. Remove arbitrary limitation in the ".+" matching case,
         similar to the change to local_exec on 2016-02-17.
