Subsequent reuse of this handle triggers an immediate crash, and\ncloning it via `curl_easy_duphandle()` copies this corrupted state into the\nduplicate. If the original handle is subsequently freed, executing a transfer\non the cloned handle causes a heap use-after-free read against the dangling\nhandle reference; alternatively, reusing the original or cloned handle while\nchanging only  `CURLOPT_WRITEDATA` (and omitting `CURLOPT_WRITEFUNCTION`)\nresults in type confusion, forcing the internal parser to interpret incoming\nserver response bytes into memory at the application-supplied write data\npointer.",
