occassionally finds spurious self-intersections that don't seem to be correct - see this minimal example of just two faces. identifies the faces as self-intersecting. If I save the file as an ascii , the file no longer shows to be self-intersecting.

I've checked the binary content of the binary file to see if there are non-displayed triangles in case zero-area triangles are simply not shown but there don't seem to be.

    How exactly did your MeshLab identify them as self intersecting? I downloaded your example, opened it with MeshLab v1.3.2 and chose `Filters > Cleaning and Repairing > Select Self Intersecting Faces` but despite clicking "Apply" they did not get marked. – Dominik Mokriš Oct 22 '18 at 19:03

    @Dominik Mokriš I am using MeshLab 64bit fp v2016.12 and I use Filters->Selection->Select Self Intersecting Faces. Just downloaded and tested again to confirm both faces are selected even though they very clearly shouldn't be. – James Oct 22 '18 at 21:11
  • @Dominik Mokriš, learnt how to use that filter from your comment. Cheers! – massisenergy Mar 10 '20 at 17:17
