C++ Dangling Reference: Safe or Risky?

In this video, we look at a subtle but dangerous C++ code snippet that compiles and runs, but invokes undefined behavior due to a dangling reference. The function returns a reference to an element inside a local std::vector, which is destroyed as soon as the function exits. We explain how this leads to invalid memory access and how stack memory reuse can hide these bugs during testing. This example is a deep dive into C++ reference lifetimes, function return safety, and debugging hard-to-catch memory issues.
