Summary

  • serialize the sampling-based CPU profile tree test so package-level test load cannot hide short-lived call paths
  • accept V8 15.2's new heap-limit reason while still requiring V8's fatal JavaScript OOM banner

The V8 15.2.124.21 upgrade itself built and passed the full platform matrix, but its release leakcheck failed twice on the profiler flake. Local validation also exposed the changed OOM reason (CALL_AND_RETRY_LAST) that would otherwise fail next.

Validation

  • leakcheck binary: 3 consecutive full-suite passes
  • TestCPUProfileNode: 20 consecutive isolated passes
  • go test -count=1 ./...
  • go vet ./...
  • actionlint
