Comment 6 for bug 481121

Hi all,

I see that this bug has been marked as a duplicate of bug 303587. I have just updated my laptop today (26/01/2010, Maxima 5.17.1) and find that the bug described in 303587 does not occur but the bug described in this report does. I see that 303587 has numerous bugs marked as duplicates. I realize that these bugs throw similar errors, but since one seems to have been resolved while others remain perhaps they should not be marked as duplicates? Specifically:

describe(plot_options); // bug raised in 303587 evaluates correctly for me
integrate((x-1)/(x^3+1),x); // this bug does not evaluate correctly, throws the errors given in this report

Some other commands that failed on my machine :
sqrt(2 * %pi);

assume(a > 0)$
integrate (1 / (x^2 + 1), x);

wxplot3d( exp(-x^2 - y^2), [x,-2,2],[y,-2,2]); // fails, but seems to be a wxMaxima specific command.

assume(omega > 0);
ode2( 'diff(y, t, 2) + omega^2 * y = 0, y, t );

The majority of these I tested via wxMaxima (they come from the tutorial http://wxmaxima.sourceforge.net/wiki/files/5/53/10minute.zip), but I checked some of them using Maxima directly and those that I checked produced the same errors as with wxMaxima.
