Selection of Signals goes crazy #493

Description

Randomly, when I open a waveform created by GHDL the selection of signals is broken.

Example:

When selecting in the top box something, the signals I can select in the box below are something completely different - maybe even random.

Often not even all signals are shown, some are missing and can't be selected at all. Same for e.g. port ouputs.

After restatring GTK Wave it sometimes works correctly and often it doesn't

Is this a known problem?

I'm using GTKWave:

$ ./src/gtkwave --version
GTKWave Analyzer v3.3.126 (w)1999-2026 BSI

And GHDL

ghdl --version
GHDL 4.1.0 (Ubuntu 4.1.0+dfsg-0ubuntu2.1) [Dunoon edition]
 Compiled with GNAT Version: 13.3.0
 llvm 18.1.8 code generator
