调用delete时出现分段错误

Question

gdb回溯:

#0  0x0040cea9 in free () from /lib/tls/i686/cmov/libc.so.6
#1  0x0033c741 in operator delete(void*) () from /usr/lib/libstdc++.so.6
#2  0x080654b6 in mesh::calculateMeanNormalsPerVertex (this=0x807d684)
    at /home/brent/Desktop/protCAD/src/math/mesh.cc:230
#3  0x0805638f in buildCubes (argc=4, argv=0xbffff3e4)
    at /home/brent/Desktop/protCAD/src/driver/executeCubes.cc:163
#4  main (argc=4, argv=0xbffff3e4)
    at /home/brent/Desktop/protCAD/src/driver/executeCubes.cc:297

声明并delete致电mesh.cc:

vector<vector<int> > faceIndicesPerVertex (vertexArray.size());
...
delete[] &faceIndicesPerVertex;    //line 230

我确定我有这个错误,但我已经尝试了几种不同的方法来调用删除,但除了上面之外似乎没有编译.有什么问题？

您不需要delete任何堆栈分配的对象,vector包括堆栈分配的对象 - 当对象超出范围时,它将被销毁并且其内存将被回收.尝试delete堆栈分配的对象会导致未定义的行为(在您的情况下崩溃).
