Brian Barrett 1454e40f0e * for some reason, was having issues with C bool vs C++ bool on odin.
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.
