[FIXED] HelloOpenCL crashes JVM running NativeKernel on AMD CPU device

[rpmfl72]

Using lwjgl 2.8.3, HelloOpenCL crashes the JVM right when it starts running the native kernel.
The other platform / device on this system (nVidia GPU) never performs the native kernel parts because it doesn't pass the CL_EXEC_NATIVE_KERNEL caps check on line 142, so I can't say if this is an AMD / CPU specific problem.
I'm on Windows 7 64-bit.

Here's the full output of HelloOpenCL, showing the device info and extensions:

...And BAM! JVM crash followed my Microsoft wanting me to report the problem.

try updating drivers - it's typically not a lwjgl bug..

[rpmfl72]

After I posted this, I decided to write a little C program to duplicate HelloOpenCL without lwjgl and test directly.
Feel free to ignore this post until I report back. 
If it still crashes, I'll just move my bug report to AMD's forums

Re: the reply posted while I was typing this.  TY, I'll check on that before I assert that all my drivers are up to date.

This happens for me too, on x64 only. I'll look into it and let you know asap.

Thanks rpmfl72, it should be fixed with the next nightly build.
