            Bug ID: 70891
          Assignee: dri-devel at lists.freedesktop.org
           Summary: CL_INVALID_BUILD_OPTIONS results in CL_INVALID_DEVICE
                    when asking for build log
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: brunojimen at gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

When you use an invalid option to build a program, you get the
CL_INVALID_BUILD_OPTIONS error, but somehow it also makes the device used for
the build invalid. So if you after that asks for the build log with
clGetProgramBuildInfo you get also a CL_INVALID_DEVICE.

Way to reproduce this bug:
1- Clone tstellard's repo of opencl-examples:
http://cgit.freedesktop.org/~tstellar/opencl-example/
2- Modify hello-world.c at line 112 to some invalid options.
3- Compile and run it, it fails at the clGetPrograBuildInfo some lines below.

Expected output:
Maybe an empty log and a CL_INVALID_BUILD_OPTIONS error.

This bug may make difficult to track problems because one may think that the
device is wrong, when all that has happened is that he have used wrong build
options.
