Segmentation fault

I am trying to use opencl as low level parallel interface in compiler.

But some executables get segmentation fault error on clCreateContextFromType() call.

Code, generated by compiler (in c-like language) listed below.

Also there is same code in assembly language.

D.5897_529 = (long int) 4228; context_properties.525[0] = D.5897_529; D.5898_530 = context_properties.525[0]; D.5899_531 = (long int) 140737351792784; context_properties.525[1] = D.5899_531; D.5900_532 = context_properties.525[1]; context_properties.525[2] = 0; D.5901_533 = context_properties.525[2]; D.5960_605 = clCreateContextFromType (&context_properties.525, 2, 0B, 0B, 0B); xorl %r8d, %r8d xorl %ecx, %ecx xorl %edx, %edx movl $2, %esi movl $context_properties.525.5739, %edi movabsq $140737351792784, %rbx movq $4228, context_properties.525.5739(%rip) movq %rbx, context_properties.525.5739+8(%rip) movq $0, context_properties.525.5739+16(%rip) call clCreateContextFromType

We can help you if you give more information(complete code which show crash and how to run sample). 

Are you sure that it is not problem with your code generation?
