The runtime option aborted on every OOM, breaking new(std::nothrow) semantics. Replace with configure-time --enable-cxx-infallible-new (default off): when on, throwing new aborts (size logged) and nothrow returns null; when off, standard new_handler + bad_alloc / null behavior is preserved. Under LTO the on-path lets the compiler prove operator new is no-throw.
