clBuildProgram and KernelAnalyzer2 crash

Hello everyone.

This simple Kernel:


struct foo{


  float a;


};



__kernel


void asdf(__global float* a) {


  struct foo asdf = (struct foo){1};


  a[get_global_id(0)] = asdf.a;


}


 


crashes clBuildProgram and the KernelAnalyzer2 for me, but only if the struct foo is initialized with a non zero value. The type of foo.a does not seem to matter, even bool crashes them. To make it clear:


struct foo{


  float a;


};



__kernel


void asdf(__global float* a) {


  struct foo asdf = (struct foo){0};


  a[get_global_id(0)] = asdf.a;


}


and


struct foo{


  float a;


};



__kernel


void asdf(__global float* a) {


  float b = 1;


  struct foo asdf = (struct foo){b};


  a[get_global_id(0)] = asdf.a;


}


do not cause a crash.

I am using  the Catalyst Driver 13.4 for my Radeon HD 7870 on Windows 7.

The KernelAnalyzer2 is at Version 2.1.880.

I hope this is the right place to post this

Re: clBuildProgram and KernelAnalyzer2 crash

Well, i guess it's good to know that it appears on Windows as well as on Linux then.

Also I remember reading "UNREACHABLE executed!" just like you mentioned in your thread, but can't reproduce it now.
