ICE - mir/interpret/validity.rs - nightly v1.45.0

ICE from mir/interpret/validity.rs compiling v0.5.4 of crate memoffset

I tried compilation with the rust release v1.45.0-nightly of 2020-04-30:

I expected to see normal compilation on several crates (e.g. memoffset v0.5.4)

Instead, this happened:

probably caused by #71140 and will be fixed by #71751 🤔 cc @oli-obk

Yes, this is a duplicate of #71612
