Segmentation fault when using std::shared_ptr with custom deleter in C++17
I'm trying to configure I'm dealing with After trying multiple solutions online, I still can't figure this out..... I'm working with a segmentation fault in my C++ application when using `std::shared_ptr` with a custom deleter. The scenario arises when I try to reset the shared pointer after it has been assigned a dynamically allocated object. I'm using C++17 with GCC 9.3, and my code looks like this: ```cpp #include <iostream> #include <memory> class MyClass { public: MyClass() { std::cout << "MyClass constructed" << std::endl; } ~MyClass() { std::cout << "MyClass destructed" << std::endl; } }; void customDeleter(MyClass* obj) { std::cout << "Custom deleter called" << std::endl; delete obj; } int main() { std::shared_ptr<MyClass> ptr(new MyClass(), customDeleter); ptr.reset(); // This works fine initially ptr.reset(new MyClass()); // Causes segmentation fault return 0; } ``` When I call `ptr.reset(new MyClass());`, I get a segmentation fault. I suspect that the custom deleter might be causing issues after the first reset, but I'm not sure why. I tried checking if the pointer was valid before resetting, but that didn't help. I've also tried using a lambda instead of a function pointer for the custom deleter: ```cpp std::shared_ptr<MyClass> ptr(new MyClass(), [](MyClass* obj) { std::cout << "Lambda deleter called" << std::endl; delete obj; }); ``` However, I still get the same segmentation fault when I try to reset it. What could be going wrong here? Is there something specific about using custom deleters with `std::shared_ptr` that I am missing? Any insights would be greatly appreciated! I'm working on a web app that needs to handle this. Could someone point me to the right documentation?
