Comment (by johnmaddock):

 Oh boy this sucks :-(

 You could work around the problem by defining
 BOOST_MATH_PROMOTE_DOUBLE_POLICY=false when building I guess.

 I don't really understand why this is being triggered, the code checks
 that 1e-800 is non-zero before calling erc_inv(1e-800) at which point it
 apparently is zero after all!  The argument values can't be changed BTW -
 they're cunningly chosen to take specific code paths and force
 initialization of all the static data.  Or I could add some try/catch
 blocks I guess, I will probably experiment with that.
