Test Failure: Transforms/InstCombine/IntPtrCast.ll

Transformation seems to be correct! (syntactically equal)

Transformation doesn't verify! (unsound)
ERROR: Value mismatch

Example:
ptr %P = pointer(non-local, block_id=0, offset=8) / Address=#x00000008

Source:
i32 %V = #x00000008 (8)
ptr %P2 = phy-ptr(addr=8) / Address=#x00000008
