Hi Ryan,

Sure, the output is as follows:

$ ./bin/mlpack_test -t LoadSaveTest/LoadArmaASCIITest
Running 1 test case...

*** No errors detected


I haven't filed a bug with QuantLib yet.  I've been trying to isolate 
the issue and wasn't sure if it was in QuantLib or boost (the fact that 
something similar is happening with mlpack suggests it's in boost - or 
how boost is being used).  I'll be sure to post a note to that ticket 
when I file one with either boost or QuantLib.  I'm also happy to test 
if you have any theories that need testing on OS X (but since I'm not 
having the issue with mlpack I'm not sure how useful it may be).

Thanks,
Kevin
