Research direction

The report provides screenshots and identifies a static object memory leak under ASan and Valgrind, but no reproducible example, source file, test, or entry point. Start by reproducing the report with pybind11 head at 2.11.1 under both tools; the work is done when the leak is isolated and a regression test demonstrates the corrected behavior.
