================
Comment at: flang/runtime/transformational.cpp:524
     mask.IncrementSubscripts(maskAt);
-    field.IncrementSubscripts(fieldAt);
+    if (field.rank() != 0) { // scalar "field" argument
+      field.IncrementSubscripts(fieldAt);

This is weird.  I thought I had a test that failed without this change, but I just tried to reproduce it, and I can't.  So I'll revert the code.
