This patch has eliminated the false convergence Giles noted on bug #824. My test circuit now fails to converge with or without the added 0V source.
I'm using Debian 13 and gcc 14 as well.
Compilation Error in options.c
The manual is a bit confusing in that both the US (behavioral) and UK (behavioural) spellings are used. Perhaps we should change the documentation to use "behavioral" everywhere to match the keyword.
Is there anything I can do to assist debugging this?
I'm unable to reproduce this using the KLU benchmarks. Can you share your circuit? Also, what operating system are you running ngspice under?
Adding 0V Source in Series with Behavioural Current Source Results in Timestep too Small
