LFS 8.3 Glibc-2.28使检查失败'stdlib / test-bz22786'

Question

我在LFS书籍的6.9节中，我的主机操作系统是Ubuntu 18.04，运行export default new Router({ mode: 'history', base: process.env.BASE_URL, routes: [{ path: 'login' beforeEnter: (to, from, next) => { console.log(to, from) // the routes if (User.loggedIn()) { next(from.fullPath) // or maybe `from.path` } else { next() } }, }] }) 时出现以下错误：

我想知道错误 stdlib / test-bz22786 是否是无害的消息？

Answer 1

stdlib/test-bz22786的旧版本需要超过2 GiB的RAM才能成功完成。如果您的系统没有那么多的RAM，而是使用交换空间，则测试将执行得非常慢，最终会超时，从而导致测试失败。

此问题已通过向后移植this upstream commit来固定在release/2.28/master上游分支上，该a commit broke malloc使用别名映射进行内存压缩。反向端口需要一些其他补丁，这些补丁也在分支中。跟踪发行分支通常是一个好主意（除了{{3}}这周早些时候，所以现在也许不是个开始的好时机。）
