Alexandra Lung focused on improving the stability of fuzz testing in the schneems/php-src repository by addressing memory management issues in C. She identified and fixed a memory leak in the Fuzzer SAPI error paths, reworking the initialization order to ensure memory allocation only occurred after proper setup. This targeted bug fix reduced the risk of memory-related crashes and improved the reliability of fuzzing tests, leading to more consistent CI results. Alexandra’s work demonstrated a strong grasp of bug fixing, fuzzing, and memory management, and she thoroughly documented her changes to support code review and future maintenance within the project.
