clAmdBlasDgemv() fails

Evaluating APPML v1.4 on x64 Windows 7 with APP SDK v2.5 and with Radeon HD 6970, driver version 8.841, the following problems manifested,

1. clAmdBlasDgemv() fails with CL_BUILD_PROGRAM_FAILURE when CPU device is selected for 32-bit application

2. clAmdBlasDgemv() fails with CL_INVALID_BUILD_OPTIONS when GPU device is selected for 32-bit application. It used to work until I upgraded the graphics card driver. However, performance was significantly slower comparing to 64-bit application

3. clAmdBlasTune is counterproductive, at least for clAmdBlasDgemv() for x64 application

Could anyone please comment if any of those issues are by design?
