Another guess (sorry if I am mistaken). Do you run this code from the main REPL thread or from another thread?
I remember I debugged hunchentoot on ECL and wanted stack trace of error happened during request handling (hunchentoot runs request handlers in separate threads). As you did, I looked at the ECL backtrace functions used in SLIME and tried to use them. Stack trace was empty. I looked at their source code and have *impression* that stack trace is only maintained for the REPL thread. Juan Jose must know better how stacktraces are implemented. But if you run from another thread, try from REPL. If you run from REPL and still doesn't have stacktrace, then my guess above does not apply.
