Comment 0 for bug 1835296

Running the 20190703 nightly MacOS build (which I believe has the new ngspice-30 library, although I don't know how to check), simulating the laser_driver or sallen_key demo project causes a hard crash of the entire KiCad application. In particular, pressing "Run/Stop Simulation" causes a segmentation fault in libngspice.0.dylib. Stack trace and version information below.

The other two demo simulation projects (rectifier, pspice) do not crash, and seem to give sensible simulation results.

The most obvious difference between the crashing (laser_driver, sallen_key) and working (rectifier, pspice) projects is that the crashing projects include external spice model libraries (e.g. ad8009.lib in laser_driver) and the working projects use only internal modules. My own projects seem to crash if they include external models, but I haven't systematically tested.

Please let me know if I can provide any additional information.
