Unexpected Segmentation Fault When Using std::vector with Shared Pointers
I'm experiencing a segmentation fault in my C++ application when trying to manipulate a `std::vector` of `std::shared_ptr` objects. The application compiles and runs fine in most cases, but I get the behavior when I try to clear the vector after modifying its contents. Here's a simplified version of my code: ```cpp #include <iostream> #include <vector> #include <memory> class MyClass { public: MyClass(int val) : value(val) {} int getValue() const { return value; } private: int value; }; int main() { std::vector<std::shared_ptr<MyClass>> myVector; for (int i = 0; i < 5; ++i) { myVector.push_back(std::make_shared<MyClass>(i)); } // Modify the vector for (auto& ptr : myVector) { ptr.reset(); // Resetting shared pointers } // Attempting to clear the vector myVector.clear(); return 0; } ``` When I run this code, I get a segmentation fault right after the `myVector.clear();` line. I've tried using both `ptr.reset();` and `ptr = nullptr;` to see if it made a difference, but the segmentation fault still occurs. I also checked that I'm not accessing any elements after clearing the vector. My environment is as follows: - Compiler: GCC 11.2.0 - OS: Ubuntu 20.04 Is there something I'm missing about the lifecycle of `shared_ptr` in conjunction with `std::vector`, or is there a best practice I should be following to avoid this kind of behavior? Any insights would be appreciated! My development environment is Windows. Thanks in advance!
