ran into exactly the same problem today with Ubuntu 16.04, 4 X K80, CUDA 8 RC, and GCC-5.3. Advice highly appreciated!

An extra bit of observation: segfaults appear in several "SolverTest", but all share the same stack trace: std::vector::_M_erase() caffe::DevicePair::compute() caffe::P2PSync::Prepare() caffe::P2PSync::Run() caffe::GradientBasedSolverTest::TestLeastSquaresUpdate()
