When I try to compile certain OpenCL code on a machine with R9 290 installed running a Catalyst 14.12 driver, the program crashes with stack overflow in amdocl64.dll when calling clBuildProgram.
The same code compiles just fine on a machine running HD 7970 with the same driver.
Below is the minimum kernel causing this to happen:
__kernel void test(__global float* srcBase, __global float* dstBase, int width, int height)
{
int x = get_global_id(0);
if(x < width)
{
int y = get_global_id(1);
if(y < height)
{
__global float* dst = dstBase + x + y * width;
__global const float* head = srcBase + y * width;
int offsetLeft = x > 0? -1: 0;
float leftFactor = x > 0? 1: 0;
float curAverage = leftFactor * (head[offsetLeft]);
*dst = curAverage;
dst += width;
}
}
}
