Thanks for the report. Unfortunately your patch seems to remove recent changes to gnuplot.c concerning the arrowplot. Please re-check.
XSPICE disable & RSHUNT
I have uploaded a fix to git branch pre-master-48: Option RSHUNT is removed from XSPICE to standard exe, so available without XSPICE compiled in.
OSDI disable & IFdevice.registry_entry
Fix uploaded to git branch pre-master-48
Thanks for the report. I will remove rshunt from the XSPICE code and move it to standard ngspice.
I have pushed the fix on cshunt_value to branch pre-master-48. rndseed is not removed, as it is set to 1 in main.c (sharedspice.c) anyway.
