Non-Ideal Wires Causing Errors about circuit-simulator HOT 3 CLOSED

Is the circuit the same one in #1 ?

from circuit-simulator.

No, it is a different one. It appears to be happening any time I connect op-amps with no feedback loop directly to the base of p or n MOSFETs.

Here is one such circuit.

After more than 2 years, I realized that the default wire resistance was too low. I have increased it from 1pΩ to 1µΩ. It may not fix the problem entirely, but this seems to be an issue with the original simulation algorithm; if you use Paul Falstad's original version and replace the wires with 1pΩ resistors, you'll get the same error.
