When you run your program interactively, it will halt on the error
condition and give you an error prompt:

    2 error>

Instead of just typing (restart 1), type (debug) to enter the debugger.
Then press the h key to see the "execution history", which is basically
a stack dump.

You can find out more about debugging, tracing entry/exit of your
functions, and setting breakpoints in Section 5 of the Scheme User's
Manual.
