I'm not sure if this helps anyone, but I experienced something similar with Cygwin a while back.
What I had to do in order to have expect working when testing GCC on Windows 10 was to defined the "CYGWIN" environment variable to "disable_pcon" (https://cygwin.com/cygwin-ug-net/using-cygwinenv.html). If I did not define this variable, then Cygwin would inject an escape sequence that would make all pattern checks fail on the output.

I don't know if Cygwin might has changed this behavior, but it was an issue in the past anyway.

Kind regards,
Torbjörn
