Summary
A systems researcher with 15 years of C++ experience describes building a Rust-style static analyzer for C++ called 'rusty-cpp' to address persistent memory safety issues like segmentation faults, memory leaks, dangling pointers, and use-after-free errors. The project aims to bring Rust's memory safety guarantees to C++ code through static analysis, addressing the author's personal frustrations with memory bugs that have caused sleepless nights and months of debugging. The article discusses the motivation behind creating this tool and its availability as an open-source project on GitHub.
Key quotes
· 4 pulledAs someone who has spent almost 15 years doing systems research with C++, I am deeply troubled by all kinds of failures, especially segmentation faults and memory corruptions.
Most of these are caused by memory issues: memory leaks, dangling pointers, use-after-free, and many others.
I've had many cases where I have a pointer that ends with an odd number. The last one literally happened last month.
It gave me so many sleepless nights. I remember a memory bug that I spent a month but still could not figure out.
