2889,Unit Test framework does things that OS X's malloc dislikes,akim.demaille@…,Gennadiy Rozental,"Using the attached file, compiled as follows, OS X's malloc reports an invalid free.  This is annoying, as we run our test with such instrumentation to catch other kinds of errors.

This is Mac OS X 10.5.6.  Boost 1.38 installed by !MacPorts.

The documentation for !MallocScribble (man malloc) reads:

   If set, fill memory that has been deallocated with 0x55 bytes.  This increases the
   likelihood that a program will fail due to accessing memory that is no longer allocated.
