Source code to reproduce the problem.

Hi,

I'm getting a internal compiler error when trying to compile a piece of code
that uses OpenMP inside of templated code. I use pointer arithmetic using a
template type inside the for loop header. I'm not sure if my code is legal for
OpenMP, but it should not cause a internal compiler error.
