perl调用mysql时出现的错误——*** glibc detected *** perl: double free or corruption (!prev):

Question

最近更新了一次perl，覆盖了原来系统自带的perl（从10.1到14.4）.更新后重新安装了所需的模块DBI和DBD::msyql，但现在每次用perl调用mysql的时候，SQL语句可以执行成功，但就是会报错。脚本如下：
注：系统为CentOS6.4,尝试了很多方法和各个perl版本都不行，这个脚本在windows下运行正常。
###################
#执行的脚本
#!/usr/bin/perl
use5.10.1;
useDBI;
my$user='root';
my$password='root';
my$dsn='DBI:mysql:database=user;host=192.168.1.93;port=3306';
my$dbh=DBI->connect($dsn,$user,$password,{RaiseError=>1,AutoCommit=>0});#
$dbh->do("DROPTABLEIFEXISTStest");
$dbh->disconnect();

具体报错如下：
***glibcdetected***perl:doublefreeorcorruption(!prev):0x00000000020a4750***

Answer 1

最终我又装回了系统之前自带的perl-5.10.1rpm-i--replacepkgsperl-5.10.1-129.el6.x86_64.rpm#（强制重新安装）现在运行时不再报错了。究其原因，应该还是因为更新perl后glibc的版本不兼容的问题。为了安装其他模块，只能再装一个版本的perl了，让两个perl并存，新的perl命名为perl-版本号。小结：1.不要随便升级系统自带的软件；2.由于CentOS是企业级的系统，为了确保系统的稳定性，很少对系统里面的软件进行升级；3.安装软件尽量使用系统自带的工具进行安装，如rpm、yum。
