Yeah, this query doesn’t crash:

SELECT (2 * ?distance AS ?circumference) WHERE {
  BIND("<http://www.wikidata.org/entity/Q111> Point(0 0)"^^geo:wktLiteral AS ?point1)
  BIND("<http://www.wikidata.org/entity/Q111> Point(180 0)"^^geo:wktLiteral AS ?point2)
  BIND(geof:distance(?point1, ?point2) AS ?distance)
}


But it reports the equatorial circumference of Mars as 40k km, which is incorrect (that’s Earth’s circumference (roughly)).
