llm_bench crashed with opencl backend

[franklei01]

Hi, I have just quickly tried new introduced llm_bench with latest version (16bc909) on Android (vivo x200 pro and xiaomi 15), and it works fine for cpu backend, but crashed for opencl backend during tg128 test.

Command to build MNN:

/path/to/build_64.sh "-DMNN_LOW_MEMORY=true -DMNN_CPU_WEIGHT_DEQUANT_GEMM=true -DMNN_BUILD_LLM=true -DMNN_SUPPORT_TRANSFORMER_FUSE=true -DMNN_ARM82=true -DMNN_OPENCL=true -DMNN_USE_LOGCAT=true"

Command to run llm_bench on Android:

/path/to/llm_bench -m /path/to/Qwen2-1.5B-Instruct-MNN/ -a opencl

Not sure if the issue is already tracked, hope this helps.
