"Essential initialization failed" when running example with --features freeze-stdlib #4292
Description
I'm getting the following when running any example as such:
cargo run --example hello_embed --features freeze-stdlib
thread 'main' panicked at 'essential initialization failed; run with RUST_BACKTRACE=1 to see Python backtrace', vm/src/vm/mod.rs:283:30
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Is this intended? Why? When and how should I use freeze-stdlib?
