I am using kdevelop on Arch Linux to build wx apps as cmake projects. A few weeks or months ago, it was just fine. Now kdevelop 22.12.3 crashes when it parses the source files after the project is successfully loaded. Once in a while, it would load and parse successfully.

I can't know if it's related to kdevelop internals, or to a problem in the cmake files of wxWidgets. Other projects not involving wxWidgets do not have this issue. The problem has been tagged 'out of scope' on the wxWidgets forum.

This backtrace is obtained from a debug build :
