Probably the infamous 'shadow line artifact'.

Those macros were more complete, and would successfully convert any isosurface.
My macros will only work properly if the centre-point and inner shape
combination can 'see' the entire outer surface. However, for my purposes (as
mentioned previously, boulders, bricks and other simple building shapes), I
think this technique does produce better meshes more quickly.

It's interesting to see the macros applied in this way - I never intended them
to be used for complete landscapes. I think better results would be obtained
for outcrops, boulders or other discrete objects that can be automatically
placed, as a supplement to heightfields or regular isosurfaces.

Encouraging though!
