@ChasingNeutrons got some NaNs in the standard deviation of the out-scatter transport cross section calculation when generating cross sections for a reactor problem. We're still not sure of where they come from, so needs checking!

I think that gfortran can take the -ffpe-trap=invalid flag and then it will crash if the NaN appears (displaying a backtrace). Maybe it will be helpful to find the origin of the NaNs?

@ChasingNeutrons, did this issue magically disappear?

Yes :'( We'll keep this open in case it reappears.
