coupler history file fails exact restart

[bandre-ucar]

Summary of Issue:

The merge of c0654db into the clm-trunk merge branch introduced a change that causes the coupler history file to not be bit for bit on a single restart test.

Note: This test is part of the 'ed' suite. All tests in the clm_short suite pass for yellowstone intel, gnu, pgi.

Expected behavior and actual behavior:

Prior to this change, all tests in the 'ed' and 'clm_short' test suites were passing, they should continue to pass with these changes.

Steps to reproduce the problem (should include create_newcase or create_test command along with any user_nl or xml changes):

./create_test -testname ERS_D_Ld5.f45_g37.ICLM45ED.yellowstone_gnu.clm-edTest

What is the changeset ID of the code, and the machine you are using:

264dd21, yellowstone, gnu

I poked at this a bit. Since the merged change incorporates three different bug fixes, I think the sanest way to debug the issues is going to be to back them out one at a time to narrow down the problem. For now I'm going to mark this test as an expected fail.

Good plan, thanks for looking into this

Note: this was reproducible in the original merge, but was an unexpected pass in 203bb6a.

closing, presumed fixed with 203bb6a.
