Comment (by ryandesign):

 We've seen similar problems with bison 3.7 in some other ports, but as far
 as I know this is not considered a bug in bison; each port needs to be
 patched to accommodate how bison now works. Try [ticket:61056 updating
 openscad to a newer version] first; maybe upstream has already fixed it.
