Note that all these failing tests are on the larger end (8 to 17  
processors) of the MPI tests and they all fail with the same error  
message.

all_gather_test-17
skeleton_content_test-8
skeleton_content_test-13
skeleton_content_test-17

../../../boost/test/minimal.hpp(123../../../boost/test/ 
minimal.hpp(123): exception "memory access violation at address:  
0x00000046: no mapping at fault address" caught in function: 'int  
main(int, char**)'

While I don't know what platform you're on, this looks like a bug in  
Boost.Test.  How much memory does this system have?  If the system is  
clean booted, idle, and you run just one single test like  
skeleton_content_test-8, does the test work correctly?  Can you run  
this test under valgrind and see if valgrind reports any significant  
problems?
