Hello all,

I don't know if I find a bug or not.

I'm simulating a circuit with a transistor. When I change the value of
power supply I get a "open circuit:internal node".

The circuit runs well on ngspice, I don't know about what I doing bad.

I paste console output:

I use Debian Sid and gnucap version of his:

ii  gnucap                              0.35-1                      GNU
Circuit Analysis package

If you need more data, please tell me.

Thanks in advance.

Salud y Revolución.
