cast the return to an int in the C++ test case, just in case. * C++ sucks. If compiling with C++ on some GNU compiler/linker combos, the initialize hook isn't automagically fired for the malloc code. Add a backup setting during opal_init, which is early enough not to cause any damage. This commit was SVN r6983.
