可恶的段错误

xuxian

我的程序在win下执行正常，到linux下，提示说有段错误。可是结果是正确的，段错误到底是什么错误啊？

gdb

xuxian

我用insight调试的，一直都正常，到程序结束的时候才弹出一个对话框，我忘记了，好像是没找到breakpoint，根本没有那个错误，可是运行的时候就有。

无双

那就调试core了

most probably you used an crazy pointer which points to some forbidden area, for example, a NULL pointer or a pointer that doesn't even exist!

Mr. kernel would send your program a SEGV signal 11 to kill it.

be careful when dealing with pointers!
