Question

请帮忙。在前端控制器架构中处理具有> 8000行代码的项目。一旦我尝试加载页面，HHVM就会因分段错误而崩溃。我在下面列出了一个已清理的堆栈跟踪，其中敏感项目替换为####。

Answer 1

众所周知，3.0.1版本会导致分段错误。版本3.1已启动yesterday，显然它修复了大多数情况¹的段错误。你应该考虑升级，也许它会起作用。

¹还存在一些问题，例如参见this one。

这已被报告为hhvm github上的两个独立问题：https://github.com/facebook/hhvm/issues/2921和https://github.com/facebook/hhvm/issues/2377。

对我跳出最多的部分是它在函数“get_tty_password”上失败，这就是它运行以提示你在键盘上输入你的mysql密码（例如，如果你键入“mysql -p” “并且它会提示你”输入密码：“。）显然，如果通过HHVM运行，这样的提示是荒谬的。

虽然HHVM segfaulting不应该是预期的行为，并且存在修复segfault本身的开放问题，但最可能的原因是您的应用程序没有在mysqli连接中设置密码。仔细检查是否设置了此密码（尝试在您使用的任何连接字符串中明确设置它，因为它可能尝试从未设置它的变量加载它。）
