Might want to use CHECK-NEXT as you were before and/or maybe some CHECK-NOT: DW_TAG between the TAG/AT/AT triples, to make sure you aren't checking attributes in some unintended TAG, etc.

tighten the test with CHECK-NOT

Oh, I'd probably use "CHECK-NOT: DW_TAG", FWIW. (because you're interested in these tags being attached to a DW_TAG_variable, not some other tag)
