App crashes after live transcribing for awhile

[jacobjiangwei]

I use the sample in here https://github.com/ggerganov/whisper.cpp/blob/master/examples/whisper.swiftui/whisper.cpp.swift/LibWhisper.swift
to do a live transcribing every 5 seconds or so.

It works great but I observed some issue:

memory gets bigger and bigger
eventually it crashes after awhile, 10~20 minutes

Here is crash stack and screenshots
Thread 520: EXC_BAD_ACCESS (code=1, address=0x20)

static struct ggml_object * ggml_new_object(struct ggml_context * ctx, enum ggml_object_type type, size_t size) {
// always insert objects at the end of the context's memory pool
struct ggml_object * obj_cur = ctx->objects_end;
