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,
