## Why The CUDAModuleNode destructor was using CUDA_DRIVER_CALL and CUDA_CALL macros that call LOG(FATAL) (throw an exception) when CUDA operations fail. During interpreter shutdown, the CUDA context can become invalid, causing CUDA_ERROR_ILLEGAL_ADDRESS when cuModuleUnload is called. Throwing exceptions in destructors is undefined behavior and causes crashes. ## How 1. Removed the throwing macros from the destructor 2. Check cudaSetDevice return value and skip cleanup if it fails 3. Ignore errors from cuModuleUnload - during shutdown these are benign since the OS will reclaim resources anyway -- This is an automated message from the Apache Git Service.
