Comment 55 for bug 1835296

As of last friday, the nightly packages have ngspice built with debugging.

I can try to debug this today, but are there step by step instructions
on how to trigger the crash? (Although I use KiCad and package it for
macOS, I do not even know where to start with ngspice and kicad.)

Thanks folks! We'll get it!
