Public bug reported:

wxmaxima 18.02.0-2 (bionic) does not evaluate variables correctly.

For the following input:

a : 1;
b : 2;
c : a / b;

wxmaxima gives:

(%i1)   a : 1;
(a)      1
(%i2)   b : 2;
(b)      2
(%i3)   c : a / b;
(c)      a/ 2

The result of (c) should be 1/2, not a/2.

Plain-text maxima (run from a terminal) gives the correct result:

(%i1) a : 1;
(%o1)                                  1
(%i2) b : 2;
(%o2)                                  2
(%i3) c : a / b;
                                       1
(%o3)                                  -
                                       2

wxmaxima 15.08.2-1 from xenial also gives the correct result, so this is
a regression in bionic.
