; Same as the dynamic-alloca-lifetime.ll X86 test, which was used to fix a bug
; in stack colouring + lifetime markers.
; This test crashed in PEI because the stack protector was dead.
; This was due to it being colored, which was in turn due to incorrect
; lifetimes being applied to the stack protector frame index.
