我正在用 c 语言模拟一个问题(3d Ising 模型),但是当问题变大时,程序停止并出现以下错误:
Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)
在程序中我有一个递归函数来完成所有工作,我怀疑错误是由于堆栈溢出(在递归函数中)但我不知道如何确定。
如果是因为栈溢出,有没有办法在不改变程序设计的情况下解决这个问题?
我正在使用 Clion IDE。
/*
* recursive function to form Wolff Cluster(= WC)
*/
void grow_Wolff_cluster(lattic* l, Wolff* wolff, site *seed){
/*a neighbor of site seed*/
site* neighbor;
/*go through all neighbors of seed*/
for (int i = 0 ; i < neighbors ; ++i) {
neighbor = seed->neighbors[i];
/*add to WC according to the Wolff Algorithm*/
if(neighbor->spin == seed->spin && neighbor->WC == -1 && ((double)rand() / RAND_MAX) < add_probability)
{
wolff->Wolff_cluster[wolff->WC_pos] = neighbor;
wolff->WC_pos++; // the number of sites that is added to WC
neighbor->WC = 1; // for avoiding of multiple addition of site
neighbor->X = 0;
///controller_site_added_to_WC();
/*continue growing Wolff cluster(recursion)*/
grow_Wolff_cluster(l, wolff, neighbor);
}
}
}
最佳答案
使用 GDB 调试器并查看调用堆栈。
gdb main
r
