Leak sanitizer triggers when python is run.\n\nPossible way to reproduce:\n```bash\nnix build --impure --expr \\\n  'with import \u003cnixpkgs\u003e {};\n   python312.overrideAttrs (oldAttrs: {\n     configureFlags = oldAttrs.configureFlags or [] ++ [\"--with-address-sanitizer\"];\n   })'\n\n```\n\nRelevant portion of the build log:\n```\n...\n./_bootstrap_python ./Programs/_freeze_module.py abc
