; This testcase, which was distilled from a HUGE function, causes problems
; because both the source and the destination of the %Y cast are converted
; to a new type, which causes massive problems.
; RUN: as < %s | opt -raise -raise-start-inst=W
int **%test(sbyte **%S) {
BB0:
br label %Loop
Loop:
%X = phi sbyte* [null , %BB0], [%Z, %Loop]

%Z = load sbyte** %Y
br bool true, label %Loop, label %Out
Out:

ret int** %W
