操作系统环境为：CentOS 5.5，内核版本：2.6.18-194.el5 x86_64

一开始使用安装向导创建服务的时候，报错！所有服务均创建失败！

修改安装向导生成的资源文件，已备后面利用srvbuildres创建服务。

首先设置一个能够解决Linux下Segmentation fault错误的环境变量： LD_POINTER_GUARD=0

在sybase用户环境下，执行下面的命令创建主服务时，

[sybase@centos5 ASE-15_0]$ srvbuildres -r ./sqlsrv.res 

报错：

主要是这句错误：*** glibc detected *** srvbuildres: free(): invalid pointer: 0x00000000183f8160 ***

原因可能有：重新释放已经释放的存储空间等。

解决方法：

设置环境变量MALLOC_CHECK_=1以使得glibc跳过检查冲突时遇到的错误。可以参考linux的man malloc结果中NOTES部分的信息。

关于环境变量MALLOC_CHECK_，不同的值代表的含义：

0 -- Do not generate an error message, and do not kill the program
1 -- Generate an error message, but do not kill the program
2 -- Do not generate an error message, but kill the program
3 -- Generate an error message and kill the program

命令如下：

MALLOC_CHECK_=1 srvbuildres -r ./sqlsrv.res

[sybase@centos5 ASE-15_0]$ MALLOC_CHECK_=1 srvbuildres -r ./sqlsrv.res
malloc: using debugging hooks
Warning: You have selected '8k' as the logical page size for the Adaptive
Server. If you plan to load dump from another database, make sure this logical

创建备份、XP、JS服务时，类似的命令为：

MALLOC_CHECK_=1 srvbuildres -r ./bsrv.res

MALLOC_CHECK_=1 srvbuildres -r ./xp.res

MALLOC_CHECK_=1 srvbuildres -r ./js.res

使用MALLOC_CHECK_=1后虽然还会报glibc invalid pointer的错误，但是最终成功创建了Sybase服务。测试ASE15.7的时候没有遇到类似的错误。

参考：glibc detected free(): invalid pointer

关于变量MALLOC_CHECK_的取值：

0 -- Do not generate an error message, and do not kill the program
1 -- Generate an error message, but do not kill the program
2 -- Do not generate an error message, but kill the program
3 -- Generate an error message and kill the program

另外，也可以在终端像设置其它环境变量一样设置： export MALLOC_CHECK_=1 或者 setenv MALLOC_CHECK_ 1
