This looks like the same error reported by Anshul Awasthi on March 27 (check
the amber mail archives).

The first thing we need is confirmation that you have run the test suite
on this machine. That will help decide whether or not the failure is
specific to your problem (in particular, try the dhfr test case, for example).

If the standard test cases work, then try a non-parallel run with your inputs.
That will at least narrow things down. Some user that has this problem is
going to have to be willing to post their input files. This is the first time
in two years that this problem has come up, which only means that we are
unlikely to be able to help much with just a stack trace....
