During May 2025, Gamehaxe focused on stabilizing the Haxe C++ runtime within the HaxeFoundation/haxe repository by addressing a memory management issue in AtomicInt. They refactored AtomicInt to decouple garbage-collected memory from cpp.Pointer, introducing a private Data class to ensure AtomicInt is no longer GC-managed. This technical approach reduced the risk of memory-related edge cases at the GC and C++ boundary, improving the reliability of atomic operations in multi-threaded environments. Gamehaxe applied expertise in C++, Haxe, and low-level memory management, demonstrating depth in native interop and runtime stability, though their contributions were limited to bug fixing during this period.
