I'm pretty sure the problem doesn't lie with cmd.exe, since I'm spawning the bash thread using the win32 CreateProcess function (the cmd.exe part was just the simplest example I could think of that reproduced the problem).
I'm already putting as much as possible in a bash script (I'm currently in escaping hell...), but that's not really an option since I don't get to choose what input I'm receiving. I guess I could write to a temporary .sh file and then feed bash that file, but it's not what I would call ideal.
