Winpdb 1.4.6 Tychod is now available for download at http://winpdb.org/download. As of this version Winpdb can debug runaway recursions. Runway recursions are an Achilles Heel of all Python debuggers. Since debugger logic is invoked with each new script frame, recursion limit is naturally hit by debugger code causing it to break down surprised, corrupted and defeated. First among its kind, Winpdb now handles recursions gallantly, effortlessly, with a smile. Try it.
