Hugging Face smolagents bug freezes AI agents with one line of math
A single line of Python code (10 ** 10 ** 8) can freeze Hugging Face's smolagents AI agent framework indefinitely, bypassing its thread-based timeout. The computation holds the GIL in a C call, preventing the timeout from ever firing. The bug, reported in issue #2473, has no fix yet and leaves agents vulnerable to silent hangs.
