I created a file - `/tmp/test-geany/test.c` which contains the single line `#include "test-include.h"`
The executable is generated from the clones of geany and geany-plugins. `geany -V` gives `geany 2.1 (git >= 9bf5769f5) (built on 2024-07-02 with GTK 3.24.41, GLib 2.80.0)`
GeanyGenDoc is the only plugin enabled.
Opening the test file in Geany and selecting either `Document Current Symbol` or `Document All Symbols` results in a crash.
The backtrace is attached.
If you do not see the same result, I will create a more realistic setup.
[Changing the line to be `#xxxinclude "test-include.h` -> no crash, but with the Status message `No valid tag at line 0`.]
