2976,:show bindings give wrong results when a variable was redefined,phercek,igloo,"Bindings displayed with '':show bindings'' do not correspond to what can be observed by printing values explicitly for example by using '':force''. The differences happen when a variable is redefined.[[BR]]
I saw the bug in 6.10.1, and 6.8.2. Pepe Iborra could reproduce it in 6.8.1 and noticed that it works well in 6.6.


Notice the value and type reported for variable ''test'' after it has been redefined in this example.
