这是什么情况？

    Linux上编译PHP遇到错误：

make: *** [sapi/cli/php] Error 1

   网上寻到解决办法：

   随之，输入命令，等了一会儿，直接显示信息如下：

You may have found a problem in PHP.
This report can be automatically sent to the PHP QA team at
http://qa.php.net/reports and http://news.php.net/php.qa.reports
This gives us a better understanding of PHP's behavior.
If you don't want to send the report immediately you can choose
option "s" to save it.  You can then email it to qa-reports@lists.php.net later.
Do you want to send this report now? [Yns]:
