     Type:  Bugs                     |      Status:  new    
Milestone:  Boost 1.39.0             |   Component:  test   
  Version:  Boost 1.38.0             |    Severity:  Problem

-------------------------------------+--------------------------------------
 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.
