metal : null-check buffer alloc to fix OOM crash (#25371) metal : null-check ggml_metal_buffer_init result to avoid OOM crash ggml_backend_metal_buffer_type_alloc_buffer used the result of ggml_metal_buffer_init without checking for NULL. ggml_metal_buffer_init returns NULL when the underlying Metal allocation fails (e.g. an out-of-memory condition), and the following ggml_metal_buffer_is_shared(res) call dereferences it, turning a recoverable allocation failure into a hard crash (EXC_BAD_ACCESS). This is easy to hit on memory-constrained devices such as iOS when a model/context exceeds the available Metal budget. Log the failure using the existing GGML_LOG_ERROR convention and return NULL so the allocator surfaces a diagnosable error up the stack instead of crashing. cont : fix log Co-authored-by: Georgi Gerganov ggerganov@gmail.com Website: https://llama.app Attestations: https://github.com/ggml-org/llama.cpp/attestations/42843565 macOS/iOS: macOS Apple Silicon (arm64) macOS Apple Silicon (arm64, KleidiAI enabled) DISABLED macOS Intel (x64) iOS XCFramework Linux: Ubuntu x64 (CPU) Ubuntu arm64 (CPU) Ubuntu s390x (CPU) Ubuntu x64 (Vulkan) Ubuntu arm64 (Vulkan) Ubuntu x64 (ROCm 7.14) Ubuntu x64 (OpenVINO) Ubuntu x64 (SYCL FP32) Ubuntu x64 (SYCL FP16) Android: Android arm64 (CPU) Windows: Windows x64 (CPU) Windows arm64 (CPU) Windows arm64 (OpenCL Adreno) Windows x64 (CUDA 12) - CUDA 12.4 DLLs Windows x64 (CUDA 13) - CUDA 13.3 DLLs Windows arm64 (CUDA 13) (preview) - CUDA 13.4 DLLs Windows x64 (Vulkan) Windows x64 (OpenVINO) Windows x64 (SYCL) Windows x64 (ROCm 7.14) openEuler: DISABLED openEuler x86 (310p) openEuler x86 (910b, ACL Graph) openEuler aarch64 (310p) openEuler aarch64 (910b, ACL Graph) UI: UI
