cc: internal compiler error: Segmentation fault signal terminated program cc1

[kapcom01]

While building an application with corteca build, randomly we receive the following error:

...

The workaround I have found is to run the following command:

sudo sysctl -w kernel.randomize_va_space=0

This command is from a related issue of buildx, which is used internally by corteca.
Related issue: docker/buildx#3170

That command disables ASLR (Address Space Layout Randomization). Turning off ASLR weakens a real security protection against memory-corruption exploits, we cannot do this on a production or exposed system. The alternative is to:

• create buildkit.toml with following content

      max-parallelism = 1
  

• Run docker buildx with options: --use --config buildkitd.toml

We also need to change the qemu multiarch image. The older multiarch/qemu-user-static image was heavily used in the past but is now deprecated. The tonistiigi/binfmt repository is the official tool actively maintained by the Docker/BuildKit core team.
