It turns out that this was already discussed in the original ticket for the 
feature, https://trac.einsteintoolkit.org/ticket/2068, and was fixed in a pull 
request 
https://bitbucket.org/eschnett/carpet/pull-requests/19/correct-error-in-vertex-centred/diff,
 which was reviewed as OK by Roland in 
https://trac.einsteintoolkit.org/ticket/2074, but never applied.  I just 
applied it.  Hopefully it will fix the problems.

I would suggest that generic.cfg should be more conservative, since it is the 
default probably used by new users, and we don't want them running into edge 
cases caused by aggressive optimisations.  Can we reduce the optimisation level 
in generic.cfg to -O2?  Then we could have a generic-no-opt or something, which 
really had no optimisations at all.
