(signal: 11, SIGSEGV: invalid memory reference) in build-script-build

[ckane]

Trying to build this on Arch, which is using the relatively newer Linux 5.12 kernel and ran into the issue. Basically when I do the cargo build step, with or without --release it fails near the end with the following error message:

error: failed to run custom build command for `ingraind v1.0.0 (/foniod)`

Caused by:
  process didn't exit successfully: `/foniod/target/release/build/ingraind-63413aae32fcee9d/build-script-build` (signal: 11, SIGSEGV: invalid memory reference)

As it is probably a difficult to reproduce environment, I went ahead and used docker to create the following Dockerfile that reproduces the error using a more vanilla Ubuntu image:

FROM ubuntu:latest

RUN apt update
RUN apt dist-upgrade -y

RUN echo "12\n5" | apt install -y tzdata
RUN apt install -y capnproto llvm-11 clang-11 curl linux-headers-generic git gcc g++ binutils pkg-config openssl libssl-dev libz-dev

RUN curl https://sh.rustup.rs -sSf > rustup.sh
RUN chmod 0755 rustup.sh
RUN ./rustup.sh -y

RUN git clone https://github.com/foniod/foniod.git

WORKDIR foniod

RUN . ~/.cargo/env && KERNEL_VERSION=5.4.0-74-generic cargo build --release
