Hi,

 

I am currently trying to experiment with fine grain SVM buffers, however I experience crashes in libamdocl64.so:

 

Program received signal SIGSEGV, Segmentation fault.

I am using the latest stable Catalyst-Version on a Kaveri-based system running CentOS-7, C-Code as well as the empty kernel are attached.

I would be greateful for any idea what might be going wrong here.

 

Thank you in advance & br, Clemens

 

PS: The driver used was:

Platform Version: OpenCL 2.0 AMD-APP (1800,5)

Fglrx 15.20.3
