| ;; GetMemInstArgs() folded the two getElementPtr instructions together, |
| ;; producing an illegal getElementPtr. That's because the type generated |
| ;; by the last index for the first one is a structure field, not an array |
| ;; element, and the second one indexes off that structure field. |
| ;; The code is legal but not type-safe and the two GEPs should not be folded. |

| ;; This code fragment is from Spec/CINT2000/197.parser/197.parser.bc, |
