Compiled as: g++ for_seg_faulter.cpp -o for_seg_faulter * Note: itdoes not seg fault with icc. Sample code: #include <string> #include <iostream> #include <fstream> #include <vector> using namespace std; int main() { vector<string> v; ifstream in("for_seg_faulter.cpp"); string line; while(getline(in, line)) v.push_back(line); // Add the line to the end // for(int i = v.size(); i >= 0 ; i--) //Using the actual v.size (21) works. As it is it seg faults. cout << i + 1 << ": " << v[i] << endl; } >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
