Start with the linked GitHub Actions job and the native crash at gluten::defaultLeafVeloxMemoryPool(), then inspect the generated hs_err_pid6158.log and core dump paths from the report. Use sbin/gluten-it.sh as the integration entry point; done requires identifying the cause and confirming the same run no longer core dumps.
