    Use a std::shared_ptr for CompilationStats · 6e887c93
    Jakob Kummerow authored
    This fixes a flaky crash when running with --turbo-stats or
    --turbo-stats-wasm.
    With dynamic tiering, it can happen that a compilation job is started
    shortly before the program/test/benchmark terminates and the main thread
    goes through its teardown sequence. When such a late job finishes, it
    still wants to report its statistics, which currently crashes due to
    UAF if the CompilationStats object, which is owned by the main thread,
    has already been deleted.
