Debugger crashes with assertion failure while using Chrome DevTools and remote debug

• Version:
  8.9.1 LTS
• Platform:
  macOS 10.13.1 (17B48) (Darwin Kernel Version 17.2.0)

Webstorm 2017.2.5
Chrome: 62.0.3202.94

No crash using Webstorm 2017.1.4

While using the Chrome DevTools and node --inspect, the node process crashes right after Chrome auto-detected the debug session as a network target.

/usr/local/bin/node[28426]: ../src/node.cc:1449:void node::InternalCallbackScope::Close(): Assertion `(env_->trigger_async_id()) == (0)' failed.

Reproduce:

• Clone Demo Project: https://github.com/Microsoft/TypeScript-Node-Starter/
• Install mongodb via homebrew
• Start mongodb via mongod --config /usr/local/etc/mongod.conf
• Open demo project in Webstorm, npm run build and configure a run configuration by adding Node.js Run Configuration and change JavaScript file to dist/server.js
• Set breakpoint in src/controllers/user.ts Line 30
• Start debugger with the Bug icon, right next to the run icon in Webstorm
• Open client site in Chrome http://localhost:3000
• Use the client site to trigger breakpoint (logged in as user)
• Resume by clicking Step Out
• Use the client site to trigger breakpoint again (logged in as user)
• Chrome: Right-click, Inspect
• Debugger crashes as shown

For me, this crash is only reproducible on one of three Mac systems with identical software versions.

首先，按照 issue 中的 TypeScript-Node-Starter 步骤，使用 Node 8.9.1、WebStorm 和 Chrome DevTools 重现崩溃。阅读 src/node.cc 中 InternalCallbackScope::Close 处的 assertion，并跟踪 NodeInspectorClient::runMessageLoopOnPause 的堆栈路径。当远程调试和 Chrome DevTools 不再导致 Node 进程崩溃时，即表示完成。
