Hi, I have a problem with openCL program, clBuildProgram does segfault / crash with newer drivers.

Please help me improve the long time bad driver reputation AMD always had. The program was working fine with older drivers and older hw (5850).

I believe all 7xxx cards are affected with all 13.xx drivers.

Tested on Linux, but windows are affected as well I think.

 

Graphics Card

MSI R7850-1GD5/OC

and

GV-R795WF3-3GD

I believe all 7xxx cards are affected.

overclocking with/without - the same.

AMD Catalyst Driver Version, and Driver History

tested 12.2-12.10 works with tweaking,

13.4 and 13.6beta crashes

Operating System

Linux Fedora Core 16x64, 18x64,  19x64

Ubuntu 10.04 LTS and 12.04 LTS

Issue Details

OpenCL program using loops unrolling,sha256, ripemd160, elliptic curves, crashes / segfaults when calling clBuildProgram.

It can be tweaked so it compiles fine with 13.xx ati drivers, but then it produces bad results.

Motherboard or System Make & Model

ASUSTeK Computer INC. P8Z68-V LX

and

Gigabyte Technology Co., Ltd. Z77-D3H

Power Supply

CPU Details

Intel i5

and Intel i3

no overclocking

Motherboard BIOS Version

stock versions

System Memory Type & Amount

Kingston HyperX 4GB DDR 3 -

2x

and

1x

Additional Hardware

nothing special

Additional Details

no viruses in Linux,hw works well,memtest and Prime95 too.

---------------

Please help, there is another issue with new drivers, they even provide incorrect results,when offending crashing part is removed from code 

I can assist with narrowing down the issue.

Please find description and crashing kernel here : http://www.filedropper.com/oclvanitygenproblem

Please do not hesitate to ask for clarification / amendments.

Thanks a lot.

best regards
