GarField++ Gas File Error: "PROGRAM STOPPED TOO MANY PRIMARIES IPRIM"

Hello everyone.

I am attempting to generate a Gas File in Garfield++ consisting 100% of Sulfur Hexafluoride (SF6) gas.

But when I run the executable, I encounter this error: " PROGRAM STOPPED TOO MANY PRIMARIES IPRIM."

For reference here is the code I am running:

#include <iostream>

#include <TCanvas.h>
#include <TROOT.h>
#include <TApplication.h>

#include "Garfield/MediumMagboltz.hh"
#include "Garfield/FundamentalConstants.hh"

using namespace Garfield;

int main(int argc, char * argv[]) {

  TApplication app("app", &argc, argv);
 
  const double temperature = ZeroCelsius+20;
  const double pressure = 1.1 * AtmosphericPressure;
 
  // Setup the gas.
  MediumMagboltz* gas = new MediumMagboltz();
  gas->SetTemperature(temperature);
  gas->SetPressure(pressure);
  gas->SetComposition("SF6", 100);

  // Set the field range to be covered by the gas table.
  const int nFields = 20;
    const double emin = 100;
    const double emax = 100000;
  // Flag to request logarithmic spacing.
  const bool useLog = true;
  gas->SetFieldGrid(emin, emax, nFields, useLog);

  const int ncoll = 10;
  // Switch on debugging to print the Magboltz output.
  gas->EnableDebugging();
  // Run Magboltz to generate the gas table.
  gas->GenerateGasTable(ncoll);
  gas->DisableDebugging();
  // Save the table.
  gas->WriteGasFile("SF6_20.gas");

}

I am not sure what I can do to mitigate this error. I tried changing the number of collisions, I tried 2, 5, 10, 20 and all have resulted in the same error.

Would appreciate any help.

Thank you.

Try increasing the lower limit of the electric field range.
