g.gui.iclass crashes the GUI

[cmbarton]

IIRC, g.gui.iclass requires 64 bit gdal and would not even launch with wxPython 2.8. I did get to launch with a version of wxPython 3 a year or more ago. But now it crashes on launch and brings down the entire GUI.

In the newest 7.2.2 binaries I've made, i.gui.iclass now only crashes the GUI. So I can at least see some kind of error in the terminal. Here it is:

/Applications/GRASS-7.2.2.app/Contents/Resources/bin/pythonw: line 3: 35164 Segmentation fault: 11 /Applications/GRASS-7.2.2.app/Contents/Resources/python.app/Contents/MacOS/python "$@"

Here are some possible causes:

I am skeptical of the last one because GRASS here is using Python 2.7.14

Ticket retargeted after milestone closed

[cmbarton]

This remains an issue in all versions of GRASS 7. Probably related to #3487

This is still an issue with 7.8 branch and master (7.9.dev), with Python 3.8.2 and wxPython 4.0.7.post2.

The ​PR456 will probably fix this.

The fix is in master and 78, please create a new ticket if it still fails.
