Hi, I've been trying to fix [1] without success: ngspice will not load another circuit if the current one contains fatal errors. Under some circumstances, this segfaults KiCad.
The only solution I see is to bring back dynamic (dlopen()/wxDynamicLibrary) loading of ngspice DLL every time the simulator is launched, since unloading and reloading again resets ngspice's internal state and releases all allocated resources. The early versions of the simulator had worked like this but later it was changed to traditional linking reportedly due to some issues on OSX with dynamic library loading. I can't find any trace of information about these DLL-related issues - so I'm calling our Mac devs here to reply if anybody remembers why this change was done. If no one gives a solid reason to stay with a hard-linked ngspice DLL, I'll revert the ngspice plugin to use wxDynamicLibrary.
