dev-lang/php-5.3.29 fails to compile. The problem seems that the ebuild doesn't respect the sandbox and read the php.ini from the host using the session.save_path ( /nucleus/php-test/ in this case with 777 permission ) from the host. Reproducible: Always Steps to Reproduce: 1.emerge -va1 =dev-lang/php-5.3.29 2.In my case FEATURES="-getbinpkg" emerge -va1 =dev-lang/php-5.3.29 3. Build complete. Don't forget to run 'make test'. >>> Source compiled. * --------------------------- ACCESS VIOLATION SUMMARY --------------------------- * LOG FILE: "/var/log/sandbox/sandbox-16573.log" * VERSION 1.0
