Comment at: llvm/lib/ProfileData/Coverage/CoverageMapping.cpp:580
       const auto &R = Segments[I];
-      if (!(L.Line < R.Line) && !(L.Line == R.Line && L.Col < R.Col)) {
+      if (!(L.Line <= R.Line) && !(L.Line == R.Line && L.Col <= R.Col)) {
         LLVM_DEBUG(dbgs() << " ! Segment " << L.Line << ":" << L.Col
