Description: Summary Fixes #55838. When an EventEmitter emits an unhandled 'error' event, V8 appends an Emitted 'error' event at: frame to the stack trace via the inspector stack trace enhancer. However, this enhancement was applied only during the default fatal-exception path (inside fatalException()), after the uncaughtException and uncaughtExceptionMonitor handlers had already been invoked, so user-registered handlers never saw the enriched stack. Root Cause fatalExceptionStackEnhancers.beforeInspector() was called inside fatalException() — the final, process-exiting path — but not inside createOnGlobalUncaughtException() which fires the user handlers first. Fix Call fatalExceptionStackEnhancers.beforeInspector(er) inside createOnGlobalUncaughtException() before emitting to uncaughtExceptionMonitor and uncaughtException. The guard er != null && typeof er === 'object' safely handles primitive throws. Testing Added test/parallel/test-process-uncaught-exception-enhanced-stack.js which verifies both a plain EventEmitter and a subclass expose the Emitted 'error' event at: frame to both handlers. $ ./out/Release/node test/parallel/test-process-uncaught-exception-enhanced-stack.js # exit 0 ✅ Signed-off-by: santusht06 115890693+santusht06@users.noreply.github.com Assisted-by: Antigravity
