hasFieldStop() crashes under certain circumstances

[dccote]

With code similar to this, it crashes in the raytracing_app I am developing. I notice there is an aperture but it is after the image and cannot be crossed at all(?)

from raytracing import *

path = ImagingPath()
path.append(Space(d=100.0))
path.append(Lens(f=100.0, label='L1'))
path.append(Space(d=200.0))
path.append(Lens(f=50.0,  label='L2'))
path.append(Space(d=100.0))
path.append(Aperture(diameter=30.0, label='Aperture'))

stop =  path.fieldStop() # This crashes, sometimes? In the raytracing app, it does, but not here.
print(stop)

rays = UniformRays(yMax=5, thetaMax=0.1, M=5, N=5)
path.display(rays=rays, onlyPrincipalAndAxialRays=False, removeBlocked=True)
