I can reproduce that one.

'ps' output shows that 'cat' and 'mintty' are both waiting for output
to finish, i.e. they're deadlocked waiting for each other's output to
be read.

Yep. This situation also happens if you hit a key that sends something
during an ongoing cat command. I think what's happening in this
particular case is that the gdb binary contains some control sequence
that triggers a response to be sent by the terminal, thus triggering
this issue in Cygwin's pty implementation.

Quite. Or just kill the cat.
