I'm having the same error (with different memory addresses).

  1. Ethminer version: 0.13.0
  2. OS: archlinux x86_64, kernel 4.15.5
  3. GPU: Radeon HD 7600M
  4. Drivers: mesa (and opencl-mesa)
  5. Command: ethminer -G --opencl-platform 0 --benchmark

Note that on linux, only the ATI (AMD) card is detected as valid for ethminer, so --opencl-platform 0 refers to this card.

This is the OpenCL driver issue. We can try help, but the problem is not on ethminer side.

Closing because not active for a month.
