Seems that v17 was not the most lucky of all releases. In our code, link, we now see several of our unit and functional tests producing double free or corruption errors or simply just hang. Note that you need OCaml to compile the code, but otherwise it is just ./configure, make, make check. Til roughly a year ago our code was regularly checked for regressions by a person of the Intel support, but with the stop the code doesn't work any more now. Maybe at some point I might provide a smaller test case, but I'm not so highly motivated to do so.
