对象达到堆限制 - 在 Chrome 上调试 Javascript SIGILL 错误？

  • 772

当我在 Wordpress 中为我的插件运行我的 js 脚本时。页面冻结、超时并返回 SIGILL 错误。我在 web 开发工具中看不到任何错误，页面只是冻结。

我使用货物安装了 minidump_stackwalk。

sudo apt install cargo
cargo install minidump-stackwalk

然后我在调试模式下运行 Chrome，

google-chrome --enable-logging --v=1

我通过 minidump_stackwalk 运行崩溃报告来解释转储文件。它给了我没有用的 chrome 库堆栈跟踪。

minidump_stackwalk ~/.config/google-chrome/'Crash Reports'/07*.dmp

当我运行这个 bash 命令（在 linux 上）时，我得到的 chrome 调试日志更有用一些。

tail -n 100 ~/.config/google-chrome/chrome_debug.log

这是我的 chrome 调试日志的输出。

看起来 JS 对象出现段错误或内存不足。可能是无限循环。

问题是，我不知道要看哪个 JS 对象。就像我说的，chrome web 开发工具与网页一起崩溃。我得到的只是一个 SIGILL 错误和崩溃报告。

我试过逐块调试代码，但行为似乎有点不稳定。有时它会与注释掉的代码一起工作，有时则不会。我每次都清除缓存。

任何人都可以帮忙吗？

    假设它不是无限循环，请尝试增加 JavaScript 堆大小以进行更深入的调试。另请参阅有关堆大小的 V8 文章，以及StackOverflow 中的这篇文章。
