Quick background -- I cannot start the .exe from a debugger; I need to attach after the fact. Binary Ninja's debugging plugin only allows attaching to a remote debug server and not a process. The target application is also 32-bit if that matters.

I have installed MinGW and the gdb packages from it. Fired up gdbserver and attached the process.

When I attempt to connect through Binary Ninja I get a status of ERROR: acquiring xml and the following stack trace

Traceback (most recent call last):

On the gdbserver side I am greeted with an error about an invalid hex digit:

D:\>gdbserver 127.0.0.1:4444 --attach 3476
Attached; pid = 3476
Listening on port 4444
Remote debugging from host 127.0.0.1
Reply contains invalid hex digit

I can't find any real information when it comes to using Binary Ninja for debugging on Windows. Is it possible at this time?
