<p>The looping macros defined in <code>cctk_Loop.h</code> use OpenMP unconditionally. If a thorn is not using OpenMP, or is using OpenMP in a manner incompatible with <code>cctk_Loop.h</code>, then this can lead to segfaults. For example, <code>cctk_Loop.h</code> uses <code>omp single</code> (that prevents certain code from executing) or <code>omp for</code> (which parallelizes part of the loops). There should be a mechanism to disable this OpenMP parallelization.</p>
