本地编译
0）执行scl enable devtoolset-7 bash，sudo yum install libasan4
1）Makefile LINK 添加-lasan
2）在CFLAGS添加
-fsanitize=address -fno-omit-frame-pointer，去掉-O -O2编译优化；
3) sed 's/-O2//g' /root/nginx-rtsp/openresty-1.19.3.2/build/nginx-1.19.3/objs/Makefile | sed 's/-O//g' >xxx; mv -f xxx /root/nginx-rtsp/openresty-1.19.3.2/build/nginx-1.19.3/objs/Makefile
