`bash` 正在泄漏内存，我应该在哪里报告它？

Question

我有一个超级简单的脚本来确认此行为：

leak.sh

#! /bin/bash
echo "Am I leaking?"

在valgrind下执行...

$ valgrind ./leak.sh

如果您更改脚本以使用 dash，Pop!_OS 的默认 shell (sh) （我假设所有 Debian 发行版） ，则运行不漏

no_leak.sh

#! /bin/dash
echo "Am I leaking?"

$ valgrind ./no_leak.sh

我可以在哪里报告这个观察结果，或者查明它是否已经得到解决？

bash版本

$ bash --version

正如 @oguz_ismail 在评论中提到的，bug-bash@gnu.org 是报告错误的合适位置。

但是，当您需要报告错误时，电子邮件的特定格式是 required/requested。

All bug reports should include:

The version number of Bash.

The hardware and operating system.

The compiler used to compile Bash.

A description of the bug behaviour.

A short script or ‘recipe’ which exercises the bug and may be used to reproduce it.

您可以在以下位置找到所有详细信息： https://www.gnu.org/software/bash/manual/html_node/Reporting-Bugs.html

最后，bash 本身内置了一个帮助脚本。从命令行调用 bashbug，它将填充大部分要求，让您填写描述和重现错误所需的步骤。

$ bashbug

填写模板后，系统会提示您是否要发送电子邮件。如果您没有连接电子邮件客户端也没关系，它会将完成的表格存储在 ~/dead.bashbug，您可以将其复制粘贴到您的电子邮件客户端。
