Ruk DoeandClaude Opus 5.5 7c06aea6f0 avcodec/libaribcaption: allocate one rect in text mode
aribcaption_trans_text_subtitle() always fills exactly one rect, but
allocated the rects array with ctx->caption.region_count entries. For a
caption without regions, such as a clear screen, that is a zero-sized
allocation, and writing sub->rects[0] goes past its end.
