Encountered this while trying to build elasticsearch-7 in enterprise-packages. It may happen in other situations but I haven't run into any others yet. There was some internal speculation that it may have to do with this code section: https://github.com/chainguard-dev/melange/blob/20a8b52707cda4c05f47454d1d56ef2866c525e7/pkg/linter/linter.go#L66C7-L66C13

Error log:

Interestingly, this doesn't happen with MELANGE_EXTRA_OPTS=--runner=bubblewrap added after make. MELANGE_EXTRA_OPTS=--runner=docker runs into the segfault, and is the default on my setup.

I also ran into this crash when trying to build datadog-agent-nvml (after having added a build-dep on python).
