Logical error in Boundarygeometry

clang 12.0.0 reports compiler warnings that sound like a serious bug:

src/Structure/BoundaryGeometry.cpp:600:50: warning: 
      operator '?:' has lower precedence than '|'; '|' will be evaluated first
      [-Wbitwise-conditional-parentheses]
            (A[2] < EPS) ? 1 : 0 | (A[2] > -EPS) ? 8 : 0);
