Does anyone know what the reasons might be to compile the Ngspice benchmark with -O0? Oh, nothing nefarious, it seems to be the (IMHO misguided) default setting

Does anyone know what the reasons might be to compile the Ngspice benchmark with -O0? Oh, nothing nefarious, it seems to be the (IMHO misguided) default settings: https://github.com/guitorri/ngspice/blob/master/INSTALL https://github.com/guitorri/ngspice/blob/master/INSTALL "--disable-debug This option will remove the '-g' option passed to the compiler and add -O2 optimisation (instead of default O0). This speeds up simulating significantly, and is recommended for normal use."
