Yes, I’m running tests for both develop and master right now and they’ll post results here in a couple of hours.

What about graph and graph_parallel? Are they also broken in current master?
Graph should be fine in master.  graph_parallel that depends on MPI is broken due to the serialization issue.  There’s also an issue with graph_parallel where some examples don’t compile in master due, apparently, to some un-merged changes from develop.  This issue was reported by Eisuke Kawashima.
The upshot is that fixing MPI serialization in master will fix both MPI and graph_parallel.  The graph_parallel/example breakage is less critical though at least one user is impacted by it.
Given that MPI and graph_parallel are entirely broken on master right now, please cherry-pick the serialization fix to master, either now or when the tests finish - it can't be worse for sure. We'll include the change in release.
Just cherry-picked these two commits into master to fix the serialization issue:

commit 0dce8d2c2ab273c488d708fb3e66dbb9c4298a79
Author: Jürgen Hunold 

commit 7d33e519b3daa01e9bb4a5545d5d084c45875e4f
Author: K. Noel Belcourt 

MPI tests are clean on master.  Graph_parallel is mostly clean, there’s one issue:

clang-darwin.compile.c++ ../bin.v2/libs/graph_parallel/test/distributed_csr_algorithm_test-1.test/clang-darwin-4.2.1/debug/distributed_csr_algorithm_test.o

In file included from ../libs/graph_parallel/test/distributed_csr_algorithm_test.cpp:25:
In file included from ../boost/graph/dijkstra_shortest_paths.hpp:25:
../boost/pending/relaxed_heap.hpp:194:53: error: no viable conversion from returned value of type 'const value_type' (aka 'const boost::optional<unsigned long>') to function return type 'bool'

                                                    ^~~~~~~~~~~~~~~~~~
which looks like a dependency on an un-merged change from graph develop.  I’ll have to track this down.
