<a href="https://github.com/KhronosGroup/OpenCL-Docs/issues/54">https://github.com/KhronosGroup/OpenCL-Docs/issues/54</a>
Clang should reject the following code:
int f0(global int * i, int (^const bl)(global int * i))
{
return bl(i);
}
int (^bl0)(global int * i) = ^(global int * i){ return *i * 2; };
kernel void f1(global int * i) {
int (^const bl1)(global int * i) = ^(global int * i){ return *i + 1; };
*i = f0(i, bl0);
*i = f0(i, bl1);
}</pre>
