Qucs-S keeps crashing...

[tomhajjar]

The latest nightly keeps crashing and I cannot pin down a specific trigger.

Crashes occur during saving a file, running simulation...etc.

Crashes also occur when opening a schematic containing subcircuits that were edited. In some case the subcircuit gained or lost pins.

I have also reported previous releases crashing when Qucs tries to open a corrupt or null data file.

As far as I know, it hasn't corrupted schematics...

I created a project using a schematic "d_Clock_2_tran.sch" that causes Qucs to close/crash. Schematic was created to chase down a bug in ngspice.

Open schematic, enable clk2 & nutmeg2, disable clk1 & nutmeg1 - run simulation.. qucs might crash

If crash:

Open schematic, disable clk2 & nutmeg2, enable clk1 & nutmeg1 - run simulation.

Qucs crashes/closes every time BUT it writes the correct data to the file and the data is visible when schematic re-opened. The schematic enable/disable selections made before crash weren't saved so they revert to schematic on HD.

If you make changes and save file FIRST, then do analysis, Qucs doesn't crash as often...
If you make changes and DON'T save file, then do analysis, Qucs closes every time...
