rustc 1.43.0-nightly (7760cd0fb 2020-02-19) static builds on alpine throw compiler error on building any orjson/maturin

[autumnjolitz]

Rust compiler states this is a bug and should be reported, so I'm listening to the compiler 😂

I use orjson in an alpine environment for fast json parsing in python. Unfortunately, the latest release and its dependencies have learned how to provoke a bug in rustc! 😮

  note: the compiler unexpectedly panicked. this is a bug.

  note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

Here's how I caused it (I use osx as a main development machine so all my linux builds are through docker 🙃

Dockerfile:

FROM python:3.7-alpine
ENV PIP_NO_CACHE_DIR=off \
    PIP_DISABLE_PIP_VERSION_CHECK=on \
    RUSTUP_HOME=/usr/local \
    CARGO_HOME=/usr/local \
    RUSTFLAGS="-C target-feature=-crt-static" \
    RUST_BACKTRACE=1
RUN apk add --no-cache build-base libffi-dev openssl-dev curl && \
    (curl https://sh.rustup.rs -sSf | sh -s -- -y --no-modify-path) && rustup install nightly && rustup default nightly && \
    python3 -m ensurepip && \
    pip3 install --upgrade pip setuptools wheel && \
    if [[ ! -e /usr/bin/python ]]; then ln -sf /usr/bin/python3 /usr/bin/python; fi
RUN python3 -m pip install --verbose orjson

Trigger the build via: docker build -f Dockerfile . and watch it explode

Just tried an earlier orjson. Same error 😳

Closing as a duplicate then. Thanks for the report!
