[Bug libstdc++/19867] New: ext/array_allocator/2.cc test failure in __exchange_and_add

["janis at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

libstdc++ test ext/array_allocator/2.cc has failed for powerpc*-*-linux*
since it was added on 2004-10-07.  On powerpc64-unknown-linux-gnu for both
-m32 and -m64 it gets SIGBUS in __exchange_and_add from atomicity.cc during
a destructor call.  The test passes on AIX and Darwin, which use the same
atomicity.h file, but all archived test results for powerpc*-*-linux* show
the failure.  It seems to fail intermittently on powerpc-unknown-eabispe.
