Please help provide information about the failure / bug.

Steps to Reproduce

Launched PowerInfer/build/bin/finetune

I’ve scanned PowerInfer with UBSAN and it has triggered on PowerInfer/ggml.c line 19835. I'm not sure whether this is an actual issue, or whether code of PowerInfer is too sophisticated for UBSAN to understand. Do you guys have any idea?
