Perhaps not, but since you have identified the fact that this function
saves something in frame 0 and does not remove it on exit, you need to
program around it when you use that function.

No, this is not a bug, this is performance in accord with documented 
specifications.  Objects in Frame 0 are persistent for the duration of
a session until removed, and are searched ahead of objects in the databases.
S+ cannot warn you about programming practices that might cause you to
get confused.
