When working on C++ projects, memory leaks are an issue that almost every developer encounters. A program that runs well in a testing environment may suddenly experience a memory spike or even an OOM (Out of Memory) error when deployed online, only to find after extensive troubleshooting that resources were not released. I previously encountered … Read more

1. Background 1. Storytelling Previously, I shared an article about <span>unmanaged memory leaks caused by C# calling C code</span>. This was a deliberately induced positive leak. In this article, we will explore the root cause of the leak from a reverse perspective. This issue is relatively easy to handle on Windows, as many people know … Read more
Memory Management in C: Avoiding Memory Leaks and Dangling Pointers In C programming, memory management is a crucial topic. Since C provides direct manipulation of memory, programmers need to manually allocate and free memory. While this flexibility is powerful, it can also lead to common issues such as memory leaks and dangling pointers. This article … Read more
Click on the aboveblue text to follow us In embedded systems, memory resources are often very limited, and memory leaks can lead to degraded system performance or even crashes. A memory leak refers to memory allocated by a program that is not properly released, gradually exhausting available memory. As a lightweight real-time operating system (RTOS), … Read more
