Invalid read when accessing std::array in C++17 after moving from a temporary object
I'm dealing with I'm writing unit tests and I've tried everything I can think of but I'm deploying to production and I've looked through the documentation and I'm still confused about I'm working with an invalid read scenario when I try to access elements of a `std::array` after moving from a temporary object in C++17..... I have a class that manages a `std::array<int, 5>`, and I'm trying to move the contents from a temporary instance into a member variable. However, when I attempt to access the elements after the move, I get an access violation behavior. Here's a simplified version of my code: ```cpp #include <array> #include <iostream> class ArrayHolder { public: std::array<int, 5> data; ArrayHolder(std::array<int, 5> arr) : data(arr) {} void print() const { for (const auto& num : data) { std::cout << num << " "; } std::cout << std::endl; } }; ArrayHolder createArrayHolder() { return ArrayHolder({1, 2, 3, 4, 5}); } int main() { ArrayHolder holder = createArrayHolder(); holder.print(); // This works fine return 0; } ``` The scenario arises when I modify the `createArrayHolder` function to return a temporary object and attempt to move it directly: ```cpp int main() { ArrayHolder holder = std::move(createArrayHolder()); // Invalid read happens here holder.print(); return 0; } ``` When I run the above code, I get a segmentation fault when trying to access `holder.print()`. I suspect it has to do with how the temporary object is being handled after the move. I've tried adding a custom move constructor to `ArrayHolder`, but that didn't resolve the scenario. What am I missing here? How should I properly manage resources when moving from a temporary object in C++17? Any insights would be greatly appreciated! Thanks in advance! I've been using Cpp for about a year now. Thanks for any help you can provide! This issue appeared after updating to Cpp LTS. This is happening in both development and production on Ubuntu 22.04. What am I doing wrong?
