Yes, I confirm the crash. The problem comes from having two files `6V6.cir` and `6V6.lib` in the same directory. Qucs-S has some priority in searching of SPICE files by extensions....

The crash has been fixed on `current` branch. The Qucs-S will substitute extension from the list only if no extension is given for the SPICE netlist. Always preserve original file...

I have tried to create a library from your project and found no issues. Everything works as expected. After inspection of your library file `OpAmp.lib` I suspect that it was...

Assume the issue has been resolved. The found bug with `params:` keyword is fixed. The fix will be available in the next release. Closing this.
