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

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CentOS 6.4,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  
    use 5.10.1;  
    use DBI;  
    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 ("DROP TABLE IF EXISTS test") ;  
    $dbh->disconnect();

具体报错如下：

从Dump上来看，指针二次释放发生在0x00000000020a4750，看内存地址隐射指针此时指向的范围在 


 01e15000-020e2000 rw-p 00000000 00:00 0                                  [heap]

可以推断跟DBI.so等下面一系列的依赖没有关系，是用户空间的错误，这种堆错误建议的可能就是新的perl和老的MySQL-devel的glibc不兼容导致的，glibc不兼容常常导致堆这里出问题
