Hello Xavier,

This issue required some tracing through the calls and I see the problem that you have mentioned and patch fixes the problem.

One comment on the patch, for the tests in the module, this line - 

self.frame_returning = None 

does not seem to have a coverage. Is there a specific significance in setting this to None and would a test help?


     def dispatch_return(self, frame, arg):
         if self.stop_here(frame) or frame == self.returnframe:
+            self.frame_returning = frame
             self.user_return(frame, arg)
+            self.frame_returning = None
             if self.quitting: raise BdbQuit
         return self.trace_dispatch

Sorry for the delay, I shall commit the fix in 3.3.
