[Ngspice-devel] current-controlled switch bug

[Eric L. <ela...@sy...>]

Hi all, 

(sorry my previous post was sent in HTML) 

I believe to have found a bug for the current-controlled switch device.
The ciruit below produces a syntax error while it shouldn't.  After some
code debugging time, I have pinpointed the error in the frontend module
inpcom.c.  I have attached a proposed patch (iswitch.patch) that solves
the problem.

I have verified past releases, and this bug has been introduced in
release 18. Release 17 doesn't produce any error.
