There's nothing special about Ruby's C core. You can use whatever 
debugger goes with the compiler you use, eg Microsoft's debugging tools 
if compiled with MSVC; gdb if compiled with gcc (although I've found gdb 
on MingW / Windows pretty unstable).

If you want a step-through debugger for Ruby, I'd look into ruby-debug. 
It's much faster than ruby's stdlib pure-ruby debugger, and also has 
nice integration eg with emacs.
