The wxMaxima port is unstable for me. I am using 7.6 on amd64 with all
patches and ports updates. wxMaxima reports version 24.02.1 with Maxima
version 5.46.0 (x86_64-unknown-openbsd7.6). Command-line maxima seems to
work fine, but it is easy to trigger a crash in wxmaxima. One way is to
call the wxmaxima internal plotting functions.
To initiate a crash:
- Start wxmaxima (in X11).
- From the main menu select Plot->Plot2d...
- Change the expression from "%" to "x".
- Set format to "inline".
- Press enter (Okay).
Equivalently:
- Start wxmaxima (in X11).
- Type "wxplot2d([x], [x,-5,5])$"
- Press shift+enter.
Generating the plot with gnuplot using "plot2d([x], [x,-5,5])$" works
normally. This also works fine using maxima itself in the terminal;
probably pointing to the issue being outside of maxima / gnuplot.
A SIMPLER WAY to trigger a crash is simply to start the configuration
menu via Edit->Configure, then attempt to close it via Cancel or OK.
Here is the backtrace from egdb from after selecting OK:

Maybe this is a wxwidgets issue?
Many thanks for any help,
