Re: [Ngspice-users] Reset library back to default state after error

[<ng...@at...>]

Please ignore my question. My code was emitting an exception whenever a 
message passed to `printfcn` in sharedspice.h started with "stderr". 
This left the library in an undefined state, so of course subsequent 
calls lead to instability...
