std::shared_ptr causing segmentation fault when used with custom deleter in C++17
I'm not sure how to approach I've searched everywhere and can't find a clear answer... I'm building a feature where After trying multiple solutions online, I still can't figure this out... I'm stuck on something that should probably be simple. I'm working with a segmentation fault when using `std::shared_ptr` with a custom deleter in my C++17 application. The scenario arises when I try to reset or release the shared pointer, leading to unexpected behavior. Here's a simplified version of my code: ```cpp #include <iostream> #include <memory> class MyResource { public: MyResource() { std::cout << "Resource allocated" << std::endl; } ~MyResource() { std::cout << "Resource deallocated" << std::endl; } }; void customDeleter(MyResource* res) { std::cout << "Custom deleter called" << std::endl; delete res; } int main() { std::shared_ptr<MyResource> ptr1(new MyResource(), customDeleter); std::shared_ptr<MyResource> ptr2 = ptr1; ptr1.reset(); // This works fine ptr2.reset(); // Causes segmentation fault return 0; } ``` I expected both resets to work without any issues, but the second reset on `ptr2` results in a segmentation fault. I've verified that `ptr1` does not go out of scope until `ptr2` is reset, so I'm unsure why this is happening. I've tried using `std::shared_ptr<MyResource>(new MyResource(), customDeleter)` directly for `ptr2`, but the question continues. Has anyone else faced this scenario? Is it a question with how I'm managing the ownership of the pointer, or is there something specific about custom deleters that I'm missing? I'm working on a API that needs to handle this. Any help would be greatly appreciated! What am I doing wrong? I'm working with C++ in a Docker container on CentOS. I appreciate any insights! For reference, this is a production web app. Thanks in advance! I'm working with C++ in a Docker container on Debian. Any advice would be much appreciated.
