I concur. The same occurs under xterm and 1.7.35-0.5 (under NT). You can pipe your yes/od command into 'head -10000' and the same applies (as long as you type the additional characters before the end of course). In fact, Cygwin does not hang, only the xterm window hangs. And, the same: with 'stty -echo' the problem does not occur. I'll add that this is not new (occurred for me at least for the last few months, even perhaps years). I'm happy that Takashi found: - a fully reproducible case - that the problem vanishes with stty -echo (that could perhaps mean a quick resolution...)
