However, on Windows, `wint_t` is `unsigned short`. Therefore when `console_getch` returns -1, the -1 value of `unsigned short` will be silently converted into the `int` value 65535. This causes `65535 == -1` to always be false, and the loop will never break. I can send a patch to qemu-devel which retypes `chr` to `wint_t` and replaces occurences of -1 with `WEOF` (an alias for `(wint_t) -1`).""" -reproduce = """1.
