Before to_poly_solve is used the kill function works just find. After using to_poly_solve once the kill function give me the following error.

I was using the following version.

Here is an example. (%i1) eq1:a+b+c=5; (%o1) c + b + a = 5 (%i2) eq2:-c+6*b-a=0; (%o2) (- c) + 6 b - a = 0 (%i3) eq3:a+b=3; (%o3) b + a = 3 (%i4) load(to_poly_solve); (%o4) C:/maxima-current/share/maxima/branch_5_46_base_861_g0e585ea73_dirty/sha\ re/to_poly_solve/to_poly_solve.mac (%i5) to_poly_solve([eq1,eq2,eq3],[a,b,c]); (%o5) %union([a = 16/7, b = 5/7 c = 2]) (%i6) kill(eq3); Maxima encountered a Lisp error:

The value $TO_POLY_SOLVE is not of type LIST

That sounds like the wxMaxima bug that properties of symbols that are changed by wxMaxima on startup are reset to the values maxima has set them to, not to the values wxMaxima has changed them to afterwards. If that is the case and the bug isn't reproducible in plain maxima I would need a lisp wizard who tells me how to resolve that bug.

This is not reproducible in Maxima 5.46.0 SBCL 2.2.5 MacOS x86 command line. Gobeli, could you try it out in the command line interface on your machine?

Then the problem definitively lies in https://github.com/wxMaxima-developers/wxmaxima/blob/main/src/wxMathML.lisp : This file of wxMaxima equips many maxima symbols with properties that somehow make maxima speak exactly the XML dialect wxMaxima understands - and applying kill() to one of these symbols actually does do what the user expects it to, except if the user has changed the symbol: I don't know how to tell the lisp file to not only change the symbol's properties, but also to add those properties to the symbol's initial properties that kill() restores the symbol to.

Any help with that lisp file is more than welcome!

The last example is in command line mode.

It happens in WxMaxima., in xMaxima, and also in command line mode Maxima.

I see, if I type kill(to_poly_solve);

The kill function will now work for other things. The next time to_poly_solve is used, it will need to be reloaded.

There have been many changes to the global def variables list. There may have been a bug that cropped in related to this issue.

Here is a command line example in windows. The attached file is a screen shot of the example where kill stops working after just the loading of to_poly_solve. Forgot to attach file.

I can't reproduce it with latest Maxima from Git on CCL (see screenshot).
