# Firefox-local: move the mel buffer into the 1-item MelBatch instead of copying
# it. The sub_tile > 0 branch is the long-audio path, where feats is n_mels * T
# floats (tens of MB for minutes of audio), and feats is dead after the
# assignment. Reported as Coverity CID 1700839 / 1700842. Pending upstream at
# mudler/parakeet.cpp; drop this patch once it lands there.
