[Carpet] Problems with checkpoint recovery on AMD machine

[Yosef Zlochower]

Hi,

  The problem seems to be with the Erik tagged version. I was actually 
using a custom
version. With the "Erik" version I get the error:
cactus_ctest: 
/home/yosef/Cactus_New/configs/ctest/build/AHFinderDirect/patch/coords.cc:313: 
void AHFinderDirect::local_coords::partial_xyz_wrt_r_mu_nu(fp, fp, fp, 
fp&, fp&, fp&, fp&, fp&, fp&, fp&, fp&, fp&): Assertion 
`jtutil::fuzzy<fp>::NE(r, 0.0)' failed.

The recovery seems to work correctly with the standard version of
AHFinderDirect.
