DynamicLibrary.prototype : lib;\nconst getter = Object.getOwnPropertyDescriptor(owner, name).get;\n\ngetter.call({});\n```\n\nCommands to run:\n```console\ncc -dynamiclib repro.c -o repro.dylib\n\nnode --experimental-ffi repro.js path\nnode --experimental-ffi repro.js symbols\nnode --experimental-ffi repro.js functions\n```\n\n### How often does it reproduce? Is there a required condition?\n\nAlways\n\n### What is the expected behavior? Why is that the expected behavior?\n\nIt should instead throw a JavaScript `TypeError`, such as “Illegal invocation” or “Invalid receiver,” without terminating the process.\n\n### What do you see instead?\n\nEach extracted getter crashes the Node.js process when called with an incompatible receiver, with either `segmentation fault` or `bus error`\n\n### Additional information\n\n_No response_","author":{"url":"https://github.com/trivikr","@type":"Person","name":"trivikr"},"datePublished":"2026-08-14T15:00:56Z","url":"https://github.com/nodejs/node/issues/65287"}
