Are the following code snippets not equivilent assuming ldc is a multiple of 2 and c is a double2*?
312 //compute leading dimension in terms of double2s...
313 ldc /= 2;
314
315 c[row + ldc * (col + 3)] = c0_3;
316 c[row + ldc * (col + 2)] = c0_2;
317 c[row + ldc * (col + 1)] = c0_1;
318 c[row + ldc * (col + 0)] = c0_0;
319
320 c[row + 1 + ldc * (col + 3)] = c1_3;
321 c[row + 1 + ldc * (col + 2)] = c1_2;
322 c[row + 1 + ldc * (col + 1)] = c1_1;
323 c[row + 1 + ldc * (col + 0)] = c1_0;

325 /*

The former gives me the correct result but the latter does not. If they indeed are equivilent, then this is a bug in the OpenCL compiler.
