cannot transmute between types of different sizes, or dependently-sized types

[brenzi]

I'm trying to build the sgx-types dependency for my project. I get the following error:

error[E0512]: cannot transmute between types of different sizes, or dependently-sized types

I'm building with

export CC=i686-linux-android16-clang
cargo +nightly-2019-10-04-x86_64-unknown-linux-gnu build --target i686-linux-android --release

The same thing worked with v1.0.9 but it fails with v1.1.0
Also, it works with other targets (armv7-linux-androideabi and aarch64-linux-android)

Is this rust isssue #61956?

don't know. anyway, I found a workaround. The sgx-types dependency can be avoided for my android crate, so that's what I did.
