GDB 打印的堆栈信息只有malloc_consolidate () 看不见别的，请指教！
问题是这样的，有一个较大的程序，在suse linux上运行一段时间之后coredump，core了之后用gdb查看信息如下：
Program terminated with signal 11, Segmentation fault.

warning: current_sos: Can't read pathname for load map: Input/output error

#1 0x00000000 in ?? ()
(gdb) q

就只有这么寥寥几行，关键是看不出来是在程序的哪里core掉，程序很大没办法一点点查。
麻烦大牛们帮帮忙，多谢了！

这个具体调试工作凭借你的程序经验检查吧, 我相信自己写的程序或者读过点程序的程序员都可以看出来.
