Here is the reduced testcase:
typedef unsigned int size_t;
extern void *memcpy (void *__restrict __dest,
       __const void *__restrict __src, size_t __n) ;

int encode_q_branch(int level, unsigned char *t, int stride1)
 {
    const int block_w= level;
    const int stride= stride1;
    unsigned char current_mb[3][stride*block_w];
    memcpy(&current_mb[0][0], t, 1);
}
