Comment (by johnmaddock):

 The following patch updates our tests to show the error:

 Then try and compile either std_real_concept_check.cpp or
 test_instantiate1.cpp.  Thankfully the inverse_gaussian distro is the only
 thing that fails.

 I haven't committed the above patch, because it'll break the regression
 tests at present.
