[cctbxbb] scitbx test crashing on mac

[Luc Bourhis]

Hi Markus,

could you do a debug build and then run that very same test script? Moreover could you run each of the 3 following variants in turn,

BOOST_ADAPTBX_FE_OVERFLOW_DEFAULT=1 libtbx.python scitbx/rigid_body.proto/tst_singular.py

BOOST_ADAPTBX_FE_INVALID_DEFAULT=1 libtbx.python scitbx/rigid_body.proto/tst_singular.py

BOOST_ADAPTBX_FE_DIVBYZERO_DEFAULT libtbx.python scitbx/rigid_body.proto/tst_singular.py 

and tell me the result?

Thanks,

Luc
