Ah, there might still be a way...

It appears that your ruby was installed from rubyinstaller.org which means that your ruby was built by gcc. I *think* that if you install the devkit that you might be able to run ruby under gdb on Windows.

Check the rubyinstaller wiki for instructions on installing the devkit:

I don't know if it puts gdb into your path or not. Regardless, try to run ruby under gdb like I suggested above and see what happens.
