'diff(x,x) gives 1 because of simplification in the simplifying function simpderiv.
We have a similar simplification for integrals:
(%i9) 'integrate(1,x);
(%o9) x
Therefore, we can do something like
(%i10) 'diff('integrate(1,x),x);
(%o10) 1
Furthermore, the following simplification is build in:
(%i15) 'diff(x,x,0);
(%o15) x
This works for an arbitrary expression too...

The examples in the documentation works for me.
The function plot2d is used for plotting. Therefore, only options which are known to plot2d can be passed. A look at the error messages shows that unknown options have been passed. E. g. the options xaxislabel and yaxislabel are not known to plot2d. the correct options are xlabel and ylabel. I have not looked at all examples in detail, but I...

This problem seems to be no longer present in Maxima 5.19post:
(%i2) integrate(exp(-pp * t^2),t,minf,inf);
Is pp positive, negative, or zero?
p;
(%o2) sqrt(%pi)/sqrt(pp)
Setting the status to pending and resolution to "works for me".

I think the function $frame does not give any useful information, when called from the user. We should make the function invisibile and introduce a CL symbol. I would like to suggest to replace "$frame" with "break-frame". This name would match the existing naming scheme for the functions of the Maxima debugger.
Remark: It is easy to replace $frame. We have only 4 calls in mdebug.lisp and one...

Documentation for intanalysis has been added to Integration.texi revision 1.45. The integral of this bug report has been added as an example.
Maxima does not give a wrong result and is able to solve the integral with the help of the option variable intanalysis. More might be possible, but this would be a feature request.
Setting the status to pending and the resolution to "Works for me"...

First, the implementation of run_testsuite has changed. Now the command will be run_testsuite(display_all=true).
Furthermore, I think this is a specific problem of wxMaxima on a Windows system. The result is displayed, when Maxima has finished its work. But with display_all = true the output is very large (several thousands of lines). It might be that wxMaxima hangs while trying to display...
