ERROR: CGAL error in CGALUtils::applyBinaryOperator
This post has NOT been accepted by the mailing list yet.
I'm getting this CGAL error when rendering one particular file on Windows 10 (64 bit):
ERROR: CGAL error in CGALUtils::applyBinaryOperator union: CGAL ERROR: assertion violation! File: /opt/mxe/usr/x86_64-w64-mingw32.static/include/CGAL/Nef_3/SNC_point_locator.h Line: 933 Explanation: wrong handle type
The file I'm rendering has two parts, selectable via the includeTop and includeBottom variables. If I include just one of the two parts, everything renders fine. If I include both, I get the error. The error message happens only the first time I render. If I re-render, then nothing happens, and nothing shows up on screen, and STL generation says "Current top level object is empty."
(In case anybody is interested, this is a finger extension exerciser.)

That's because F6 CGAL caches, and with an error the results are empty, but it still has been evaluated so doesn't try again.
Either change something or do Design/Flush_caches then re-render.
