Worked on the Verilator repository to enhance reliability and memory management in file content handling. Focused on correcting VFileContent reference counting during FileLine object copies, addressing a subtle bug that could lead to memory leaks or dangling pointers in long-running simulations and CI environments. The solution involved implementing a proper copy constructor in C++, demonstrating careful attention to memory management and software development best practices. No new user-facing features were introduced during this period, as the primary goal was to improve code health and stability, laying a solid foundation for future enhancements and ensuring maintainability in a complex C++ codebase.
