Worked on stabilizing cross-platform builds for the google/perfetto repository by addressing a Windows-specific build issue related to the StdinThread function. Focused on aligning the function signature in subprocess.h with its Windows implementation in subprocess_windows.cc, this change ensured ABI consistency and prevented downstream build failures for both users and continuous integration systems. Applied strong C++ and build systems expertise to debug and resolve the mismatch, improving reliability for Windows users and downstream consumers. Demonstrated careful attention to cross-platform development practices, contributing to the long-term maintainability and stability of the codebase without introducing new features during the development period.
