;; 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,
;; file post_process.c, function build_domain().
;; (Modified to replace store with load and return load value.)
