Valgrind's libpthread implementation is incomplete;  for some functions it
pretends to implement them but just does a cheap imitation (a "kludge" --
maybe we should not use this word as it's meaning doesn't seem to be
widely known), in the hope that this is enough;  often it is.
Unfortunately, it seems that for your application it's not enough.  If you
are keen, you could try hacking coregrind/vg_libpthread.c to implement
sem_destroy() and any other "kludged" functions to a sufficient level for
things to work.
