I've finally got the testsuite able to run with ubsan and asan enabled, with a few hacks in place. That revealed quite a few problems!
The first patch in this series just frees some memory which wasn't being deallocated. That isn't really a problem, as the tests exit immediately anyway, but it's nice to get clean reports from leak checkers. * testsuite/18_support/new_delete_placement.cc: Don't allocate (and leak) memory for arguments to placement delete. * testsuite/20_util/addressof/1.cc: Don't leak memory. * testsuite/22_locale/locale/global_locale_objects/3.cc: Likewise. * testsuite/23_containers/unordered_multimap/insert/55028-debug.cc: Likewise. Tested powerpc64-linux, committed to trunk.
