I am getting a segmentation fault when attempting to use Boost.Test. I suspect that I don't have something set up correctly -- your assistance in remedying this would be appreciated. I am using clang++-mp-3.3 as installed by MacPorts on OS X 10.8.4. Here's the crash, which occurs after Boost.Test reports "*** No errors detected". Program received signal EXC_BAD_ACCESS, Could not access memory.
