I'm not sure what causes this, so I'll stick to a generic title..

.clif Test Case

function u0:1(i64 vmctx) {
    gv0 = vmctx
    heap0 = static gv0

block0(v3: i64):
    v1 = iconst.i32 0
    v2 = iadd v1, v1
    store little v1, v2
    return
}

Extra Info

A quick git bisect takes me to cb48ea406eea535b3108853b7b680d9aa21eb14b. That's probably not too useful though.
