[boost] [Test] Memory leak with boost v1.40 under gcc 4.2 for x86_64 in Snow Leopard

[First time poster to boost]

Compiling for the default x86_64 produces a memory leak in the test  
framework, but the same program compiled for i386 does not. Mac OS X  
Snow Leopard gcc 4.2 with macports boost 1.40.0 (same memory leak seen  
in v1.39 macports also). The memory leak only occurs with multiple  
test cases or test suites. Set the define in my test program to remove  
the extra test case, and the leak dissappears.

Could not find this problem on the list, nor the 'net.

Output is:
<code>

boost-test.cpp  -I/opt/local/include  -g
