VAD coredump (whisper-server)

[bkervaski]

I found an issue that's causing a core-dump with VAD, the audio file being processes is fine and I can re-process it and it works the second time, it's a stereo PCM wav file.

The whisper-server startup command is:

bin/whisper-server -m models/ggml-large-v3.bin --port 8080 -nc -sns --diarize -t 8 --vad --vad-model models/ggml-silero-v5.1.2.bin

Here's the log output prior to the core dump, I also have the actual core dump if needed:
