llama.cpp 错误导致 M-RoPE 嵌入时发生内存溢出

llama.cpp 库中的一个错误允许它在处理 M-RoPE 嵌入时读取超出已分配内存的区域,M-RoPE 是 Qwen2.5-VLQwen2.5-Omni 等模型使用的功能。这种堆缓冲区溢出发生的原因是该库错误地计算了位置所需的内存,导致输出损坏或不连贯。一个已验证的开放式拉取请求 #28910 通过调整位置的处理方式来修复此问题。 AI

影响 此错误可能导致在使用 M-RoPE 模型的 llama.cpp 的应用程序中出现输出损坏或不稳定。

    llama.cpp 读取 M-RoPE 嵌入时超出其自身 pos 缓冲区,且未报告任何错误

    <p><strong>TL;DR</strong>: <code>include/llama.h</code> says the <code>pos</code> array "must have size of n_tokens", and that if you pass <code>NULL</code> "the token position will be tracked automatically". For a model that uses multiple positions per embedding — M-RoPE, which …
