I can confirm that the test hangs on powerpc if more then one thread is used. The problem seems to lie somewhere in the thread cleanup routines of TBB, i.e. the parallel code of MIA is run, and then tbb::parallel_reduce/tbb:parallel_for do not return.
According to the changelog the TBB release currently available in debian/sid is the very first that supported 32 bit powerpc, and that version is quite old (from 2011). I will check what happens with the latest version of TBB (4.1 update 2). -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
