Any chance you could bisect Cygwin to help finding the culprit?
The culprit is commit 252a07b0ad3353abcd0fcd9b1b65ff977acd679e Author: Takashi Yano <takashi.yano@nifty.ne.jp> Date: Fri Apr 3 13:07:35 2015 +0900 Cygwin hangs up if several keys are typed during outputting a lot of texts. * fhandler_tty.cc (fhandler_pty_slave::read): Change calculation of "readlen" not to use "bytes_in_pipe" value directly. Reverting that commit fixes the problem. To test, compile and run the attached file. $ gcc gdbstc.cc $ ./a 1-inferior-tty-set /dev/pty3 2-gdb-set height 0 3-gdb-set non-stop 1 4-file-list-exec-source-files 5-file-list-exec-source-file 6-gdb-show prompt 7-stack-info-frame 8-thread-info 9-break-list q *** using gdb =thread-group-added,id="i1" ~"GNU gdb (GDB) (Cygwin 7.10.1-1) 7.10.1\n" ~"Copyright (C) 2015 Free Software Foundation, Inc.\n" ~"License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>\nThis is free software: you are free to change and redistribute it.\nThere is NO WARRANTY, to the extent permitted by law.

In bad cases (bug present), the program hangs and doesn't complete until the gdb process is killed from a different terminal. In good cases it runs to completion. Ken
