mysql2 分段错误位于 0x0000000000000000

Question

我从 FreeBSD 11.3 上的端口安装了 redmine，现在尝试从浏览器访问它，但它崩溃了。错误日志显示以下内容。

    /usr/local/lib/ruby/gems/2.6/gems/activesupport-4.2.11.1/lib/active_support/core_ext/object/duplicable.rb:111: warning: BigDecimal.new is deprecated; use BigDecimal() method instead.

输出更长，我将其缩短，这是堆栈中最上面的错误。我不确定哪个社区更适合解决这个问题，所以我决定先在这里问。

我今天在 ubuntu 20.04 和 msql2 -v 0.5.1 上遇到了类似的问题。问题解决：

sudo apt remove libmysqlclient-dev
sudo apt install libmariadbclient-dev
gem install mysql2 -v '0.5.1' 

这里有更详细的描述： https://github.com/brianmario/mysql2/issues/1075

或者对于更高版本：

sudo apt remove libmariadbd-dev
sudo apt install libmariadbd-dev
gem install mysql2 -v 'your version'
