555 timer with non-ground negative supply about circuitjs1 HOT 3 CLOSED

I had a chance to take a look at the code.
Here is a possible issue, in that the check volts[N_OUT] > volts[N_VIN]/2 does not seem to take into account that the ground pin may be connected to something other than ground. It should probably become something like volts[N_OUT] > (volts[N_VIN]+groundVolts)/2 after moving the definition of groundVolts to the top of the method.
Same here, where the volts[N_CTL]/2 expression does not yield the expected value in case of a non-ground negative supply. (volts[N_CTL]+groundVolts)/2 should fix it, I think.

I cannot find anything else in that file, so perhaps fixing those two items would be enough?

yes, I think that is right.
