ggml-cpu : disable PCH and fix CACHE_LINE_SIZE ambiguity to fix heap corruption (#28882) Disable the ggml-cpu precompiled header and remove the std::hardware_destructive_interference_size branch from CACHE_LINE_SIZE. The PCH force-includes ggml-impl.h before ops.h, which pulls in via / and defines __cpp_lib_hardware_interference_size. This makes the C++ kernels use CACHE_LINE_SIZE = 256 (hardware destructive interference size) while the C work-buffer sizing code in ggml-cpu.c always uses the fallback 64. The mismatch undersizes the rope work buffer by (CACHE_LINE_SIZE/4 - 16) * n_threads * 4 bytes, causing a heap-buffer-overflow that corrupts the heap and later crashes in ggml_compute_forward_rope_flt. Disabling the ggml-cpu PCH restores the natural include order so ops.h is processed before , keeping CACHE_LINE_SIZE consistent. Removing the std::hardware_destructive_interference_size branch makes the value deterministic and include-order independent. ref: #28858 Assisted-by: pi:llama.cpp/DeepSeek-V4-Flash-Vision-Exp Website: https://llama.app Attestations: https://github.com/ggml-org/llama.cpp/attestations/47314928 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 10.0) 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) - CUDA 13.4 DLLs Windows x64 (Vulkan) Windows x64 (OpenVINO) Windows x64 (SYCL) Windows x64 (ROCm 10.0) openEuler: DISABLED openEuler x86 (310p) openEuler x86 (910b, ACL Graph) openEuler aarch64 (310p) openEuler aarch64 (910b, ACL Graph) UI: UI
