我现在做的一个项目是把它从linux（32bit）移植到linux（64bit）。配置如下：
Linux（SuSE11）+ Sybase + tomcat1.6
我负责的是后台程序（c/c++开发，调用了C++ 开源库Poco和Linux C的头文件）。前期的Poco库和Sybase的64位动态链接库都已经编译连接好。只是在运行的时候就直接报错，如下：
smm@linux:~> smm_agent: malloc.c:3096: sYSMALLOc: Assertion `(old_top == (((mbin ptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct mallo c_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) >= (unsigned lo ng)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size _t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((un signed long)old_end & pagemask) == 0)' failed.
这个我网上查了说是内存问题，可具体是什么又很难定位。
以下是debug信息：
