Hello all, I looked at trac 7084 http://trac.sagemath.org/sage_trac/ticket/7084
* If I enter the commands from test section in
sage: var('m')
m
sage: assume(n, 'integer'); assume(m, 'integer')
into Sage session (4.2), then Sage hangs. I have to enter also var
('n') to continue in Sage notebook without hanging. However, if I
run ./sage -t devel/sage/sage/symbolic/assumptions.py , then the tests
are O.K. It is to be surprising for me. Why does
sage: assume(n, 'integer'); assume(m, 'integer')
hang Sage in notebook and not when running tests?
* I think that forget does not work as excepted, see the following
Sage session and the last three outputs.
