Confirmed.  Reduced testcase:

typedef unsigned char uint8_t;
typedef unsigned long long uint64_t;
typedef struct SPS {
        uint8_t(*top_borders[2])[16 + 2 * 8];
        int             neighbor_transform_size;
} H264Context;
static void fill_caches(H264Context * h, int mb_type, int for_deblock)
{
  h->neighbor_transform_size = 0;
}
static inline void backup_pair_border(H264Context * h, uint8_t * src_y, int
linesize)
{
  *(uint64_t *) (h->top_borders[1][linesize]) = *(uint64_t *) (src_y +
linesize);
}
void hl_decode_mb_internal(H264Context * h, int simple, int *linesize)
{
        if (!simple) {
                uint8_t *pair_dest_y;
                backup_pair_border(h, pair_dest_y, *linesize);
                fill_caches(h, 1, 1);
                (*linesize)++;
                fill_caches(h, 1, 1);
        }
}
