Unexpected segmentation fault when using std::list with iterators in C++20
I'm having a hard time understanding Hey everyone, I'm running into an issue that's driving me crazy... I'm maintaining legacy code that I'm stuck on something that should probably be simple..... I'm experiencing a segmentation fault when iterating over a `std::list` in my C++20 application. My code is designed to update elements in the list based on a condition, but it seems to crash when I try to modify elements directly through the iterator. Here’s a simplified version of what I’ve tried: ```cpp #include <iostream> #include <list> int main() { std::list<int> myList = {1, 2, 3, 4, 5}; for (auto it = myList.begin(); it != myList.end(); ++it) { if (*it % 2 == 0) { *it *= 10; // Attempting to modify the element } } for (const auto &value : myList) { std::cout << value << " "; } return 0; } ``` When I run this code, I expect to see the modified list printed, but instead, I receive a segmentation fault. I have confirmed that my list has valid elements, and the iterator appears to be properly initialized. I checked for common pitfalls like removing elements during iteration, but I'm not using `erase`, just direct modification. I’ve also tried using `std::list::iterator` explicitly instead of the auto keyword, but that did not change the outcome. Could it be that there's a specific scenario with the way I'm modifying the elements in a `std::list` using iterators in C++20, or might I be overlooking something in my environment setup? Any insights would be appreciated! Is there a better approach? Am I missing something obvious? The project is a REST API built with C++. I'd be grateful for any help. I'm developing on macOS with C++. Is there a better approach?
