I'm trying to install wasmer with Ruby 2.6.3 and Rust 1.46.0, but install fails with a bunch of errors like error:externfn uses typeinstance::RubyInstance, which is not FFI-safe (rutie issue #128. I have a number of other rutie projects and those are fine (I started getting the same issue when Rust 1.46 came out).

Describe the bug
I'm trying to install wasmer with Ruby 2.6.3 and Rust 1.46.0, but install fails with a bunch of errors like
error:
externfn uses type
instance::RubyInstance, which is not FFI-safe
(rutie issue #128. I have a number of other rutie projects and those are fine (I started getting the same issue when Rust 1.46 came out).Steps to reproduce
gem install wasmer
Expected behavior
Successful install.
Actual behavior
