on vector check,
I find the vector has something wield,


compiler_abs_char2:

Raw:
  6 -4 -1 -5 -7 8 3 -3 1 -2 -4 3 3 -5 8 6 -5 5 -4 -6 -6 4 4 -1 4 8 3 -6 
-4 -3 0 -7
CPU:
  6 4 1 5 7 8 3 3 1 2 4 3 3 5 8 6 5 5 4 6 6 4 4 1 4 8 3 6 4 3 0 7
GPU:
  4 4 5 5 8 8 3 3 2 2 3 3 5 5 6 6 5 5 6 6 4 4 1 1 8 8 6 6 3 3 7 7 
compiler_abs_char2()    [FAILED]
     Error: !memcmp(buf_data[1], cpu_dst, sizeof(T) * n)
   at file /home/robinhe/CL/beignet/utests/compiler_abs.cpp, function 
compiler_abs_with_type, line 136

element2 seems over write the data of elemet1?
