Comment (by kencu):

 Hmm. Another possible approach...I see there is a clang option `-fno-use-
 cxa-atexit` that might help here. See <http://clang-
 developers.42468.n3.nabble.com/where-should-target-specific-flags-be-set-
 tt4035181.html#none> and <http://lists.llvm.org/pipermail/llvm-
 bugs/2011-February/016717.html>.

 Assuming non-trivial C++ destructors still somehow work with this flag
 added, and if this works to fix the problem, it could be made the default
 easily enough.
