I don't buy this. 10.1.018 has been a version we have been recommending for
years because of it's stability. I would be surprised to find an error now.
More likely this test case has VERY bad initial structures since just
naively setting up end points and allowing an interpolation will lead to
vlimit errors in NEB. Chances are there is a division by a very small number
occurring here, due to the images being on top of each other, and some
compilers are more sensitive to rounding this to zero than others. It would
probably be better if an actual restart from an equilibrated set of
coordinates was used as the test case, this would likely give a more
reliable regression test. I'm cc'ing this email to Christina who I hope can
put together a more realistic test case.

We need volunteers to fix this ASAP hence why I posted it.
