--- Comment #2 from David Binderman <dcb314 at hotmail dot com> ---
Reduced C++ code seems to be:

namespace geom {
class Envelope;
}
using geom::Envelope;
constexpr double quiet_NaN() { return __builtin_nan(""); }
constexpr double DoubleNotANumber = quiet_NaN();
namespace geom {
double expandToInclude_x;
struct Envelope {
  Envelope() : minx(DoubleNotANumber) {}
  void expandToInclude() {
    if (expandToInclude_x < minx)
      minx = expandToInclude_x;
  }
  double minx;
};
} // namespace geom
Envelope ComponentJumpCheckercomputeEnvelope() {
  Envelope env;
  env.expandToInclude();
  return env;
}
