Perplexing, it probably needs someone with an interest in numerics to debug 
it on that platform to figure this out, especially as the asinh code for 
that test case is a completely trivial:

return( log( x + sqrt(x*x+one) ) );

We might be able to eliminate a couple of obvious ones though: can you find 
out what std::sinh(3.8F) returns?  First 9 digits please :-)

Then what happens if you add a boost::math:: qualifier to the asinh call in 
asinh_test.hpp  and re-run the test?

I'm also pleased to see I'm not the only person who mis-types "math" as 
"match"!! :-)
