alpine:edge compilation failed starting in v1.14.0+ (/usr/include/fortify/stdio.h:82)

[Mizux]

Seems HiGHs latest/v1.14.0 do not compile on alpine:edge anymore...

Protocol

A simply way to reproduce it is to use this Dockerfile (placed in the root dir of a fresh git clone).

./Dockerfile:

# Create a virtual environment with all tools installed
# ref: https://hub.docker.com/_/alpine
FROM alpine:edge AS base

# Install system build dependencies
ENV PATH=/usr/local/bin:$PATH
RUN apk add --no-cache git build-base linux-headers cmake
CMD [ "/bin/sh" ]

FROM base AS env
RUN cmake -version

FROM env AS devel
WORKDIR /home/project
COPY . .

ARG CMAKE_BUILD_PARALLEL_LEVEL
ENV CMAKE_BUILD_PARALLEL_LEVEL=${CMAKE_BUILD_PARALLEL_LEVEL:-4}

FROM devel AS build
RUN cmake -S. -Bbuild
RUN cmake --build build --target all -v
RUN cmake --build build --target install

FROM build AS test
RUN CTEST_OUTPUT_ON_FAILURE=1 cmake --build build --target test

then use the following cmds:

# verify my HiGHS clone 
$ git rev-parse --abbrev-ref HEAD
latest
$ docker build --target build --progress=plain . 

Observed

compilation failed

Expected

compilation pass

Dev Note

FYI, testing using v1.13.1 compilation pass, so it seems to be a newly regression...

$ git checkout v1.13.1
$ docker build --target build --progress=plain .

Potential workaround: disable IPO/LTO on alpine...
