+cpp程序在Linux下生成dump文件。
+1.编辑：/etc/sysctl.d/99-core-dump.conf (99是优先级规则)
+2.应用：sudo sysctl -p /etc/sysctl.d/99-core-dump.conf
+临时应用：sudo sysctl -w kernel.core_pattern=/tmp/coredump/core.%e.%p.%t
+3.sudo mkdir -p /tmp/coredump
+4.gdb /home/xx/a.out /tmp/coredump/core.a.out.13112.1738999997
+5.使用bt(用于显示程序崩溃或暂停时的调用堆栈（Backtrace）)查看。
