Compiler crashes

Hello all,


I am currently working on a application in python and opencl (using pyopencl) to accelerate computation of multiple small optimization problems. I took a C implementation of the Levenberg-Marquardt algorithm and with some code generation tools I am able to produce kernels. I appended such a generated kernel to this question.


This kernel works, but only some of the time, it often crashes during kernel compilation.


My setup is as follows:

Machine 1, Gentoo x64, Radeon HD 280X

ati-drivers-13.12:  works most of the time, gives random failures during kernel compilation

ati-drivers-14.6_beta1: always crashes during compilation


Machine 2, Windows 7, Radeon HD 260x

latest drivers: works only if '-cl-opt-disable' is set, crashes otherwise.


I hope someone is able to suggest a solution to this compiler crashing, or, perhaps AMD's compiler team can use it as a test case for their drivers.
