With hardware decoding I had crashes after av_hwframe_transfer_data. It looks like a clean dst frame is needed and can not be reused with some hardware codecs.

frame->data[i] = st->pict->data[i];
frame->linesize[i] = st->pict->linesize[i];
frame->data[i] = sw_frame->data[i];
frame->linesize[i] = sw_frame->linesize[i];

av_free should only free the allocated AVFrame struct not the data itself I think.
