\*\*Hello, I´m trying to code a kernel using opencl. But Im stuck with a stranger error inside of the kernel function.
The flow is more or less like this:

```
__kernel function1() {
      struct mytype;
      function2(&mytype);
 }

 function2(struct *mytype) {
      uchar *ptr = mytype->value2;
      function3(ptr);
 }

 function3(byte* ptr) {
      uint16 v1 = 10;
      uint16* ptr2 = (uint16*) ptr;
      *ptr2 = v1 >> 8; 
 }

 struct mytype {
       uchar value1[8];
       uchar value2[8];
       uint key[52];
       uint bufleft;
  } 

```

The code fails when executing the assignment:

```
*ptr2 = v1 >> 8;

```

But the only message I receive is "clFlush(): CL\_UNKNOWN\_ERROR"
If I try to assign a value and not an expression, than it works.
I´m using OpenCL 1.2 CUDA in Ubuntu
