This is what it reduced to:
define i8* @zot() safestack {
bb:
%tmp = alloca i8*, align 8
%tmp2 = bitcast i8** %tmp to i8*
br label %bb3
bb3: ; preds = %bb3, %bb
call void @llvm.lifetime.start(i64 8, i8* nonnull %tmp2)
%tmp4 = call i32 @wombat(i8** nonnull %tmp)
indirectbr i8* undef, [label %bb3]
}
declare i32 @wombat(i8**)</pre>
