Simplified test case:
// NaN start fraction
// https://github.com/libgeos/geos/issues/1077
template<>
template<>
void object::test<7>
()
{
input_ = fromWKT("LINESTRING EMPTY");
double start = std::numeric_limits<double>::quiet_NaN();
double end = 0.1;
result_ = GEOSLineSubstring(input_, start, end);
ensure(result_ == nullptr);
}

Does this indicate we should sanitize all numeric inputs (e.g. by replacing NaN with 0, or else throwing)?
What do other C libs do?

I think we just need more testing of NaN inputs. I don't think there's a universal right way to handle them.
