I've seen these these errors as well at one point or another but never could quite find out what the issue is. I've only seen this on relatively new operating systems and was hoping that I could avoid these errors by just upgrading the Threading Building Blocks and Boost. I've done the former last night, and hope to get around to doing Boost sometime soon. One thing that surprises me is that the FETools::compute_embedding_matrices function uses tasks (handled by the TBB) whereas the tests you cite use threads (handled by Boost). I don't know where the connection is. So in essence I'm afraid I'm not of much help. Try if the TBB upgrade helped some, otherwise I'll put the Boost upgrade at the top of my list.
