Hi,
The following kernel gives segmentation fault (see transform algorithm with constant iterator · Issue #507 · boostorg/compute) on AMD (works on NVIDIA).
#define boost_pair_type(t1, t2) _pair_ ## t1 ## _ ## t2 ## _t
#define boost_pair_get(x, n) (n == 0 ? x.first ## x.second)
#define boost_make_pair(t1, x, t2, y) (boost_pair_type(t1, t2)) { x, y }
#define boost_tuple_get(x, n) (x.v ## n)
typedef struct {
int v0;
int v1;
} boost_tuple_int_int_t;
inline int fun(boost_tuple_int_int_t x){ return 10; }
__kernel void copy(uint count, __global int* _buf0, __global int* _buf1)
{
uint index = get_local_id(0) + (512 * get_group_id(0));
for(uint i = 0; i < 4; i++){
if(index < count){
_buf0[index]=fun((boost_tuple_int_int_t){ _buf1[index], 7});
index += 128;
}
}
}
However, when I replace
_buf0[index]=fun((boost_tuple_int_int_t){ _buf1[index], 7});
with
boost_tuple_int_int_t value = {_buf1[index], 7};
_buf0[index]=fun(value);
it works perfectly.
It may be connect to Another bug in OpenCL compiler which was marked resolved.
