Can you send example code that reproduces this problem?

I am trying to use PETSc-dev for a while in a project at my
university. I need to use the GPU for matrix-vector operations and the
code that I'm working was already implemented using PETSc, obviously I
choose the PETSc ViennaCL-GPU solution. The original code works
perfectly, but when I use the GPU parameters, a SEGV occurs in some
test cases.
Valgrind says that is a problem with PetscMallocAlign at memalign but,
some times, it says that the problem is MatGetDiagonal.
I'm sending the configure.log because I don't know what are the cause
of the problem (hope the problem is the configuration), and I would
like to know if some similar problem were reported by PETSc-ViennaCL
users and PETSc-CUDA users too.
PS: My computer has a top AMD GPU and I'm not sure that I can find a
NVIDIA GPU computer to test my code, so OpenCL solutions are better to
me then CUDA.
