Agreed on divide-and-conquer. There is no other way. Valgridn et al may move
some code to registers for subtle changes.

By "mocking" the exact same (compile and run-time) options used by R CMD
check. You can trace that down.  Things depend a little on whether you do or
do not use user-library-paths for .libPaths() or not, whether you use
per-user compile flags etc pp.
