The Windows executable of ngspice-25 crashes if an input file containing a .save line is rerun after editing and saving. I have tested many input files with and without a .save line on Windows XP and 7. Same problem is observed in all with a .save line but not in any without such a line. A simpel example:
v1 1 0 dc
r1 1 2 1k
r2 2 0 1k
.dc v1 0 1 1m
Thanks in advance for your attention.
