Test Failure: Transforms/InstCombine/IntPtrCast.ll

define ptr @test(ptr %P) {

Transformation seems to be correct! (syntactically equal)

define ptr @test(ptr %P) {

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

Example:
ptr %P = undef

Source:
i32 %V = #x00000000 (0)	[based on undef value]
ptr %P2 = 0x0
