Comment (by kevinoid):

 I recently encountered a similar issue in [http://quantlib.org QuantLib]
 and brought it up for [http://lists.cs.uiuc.edu/pipermail/cfe-
 dev/2014-April/036279.html discussion on the cfe-dev mailing list].  I'm
 not sure if it is the same issue, but the issue I was experiencing was due
 to C++11 ABI incompatibility for static initialization which occurred due
 to the `const static` variables in `lanczos_initializer`.

 To test if this may be the issue in your case as well, try running the
 following commands:

 {{{
 nm /usr/local/lib/libmlpack.dylib | c++filt | grep ::num$ | fgrep -v
 'guard variable'
 nm explore | c++filt | grep ::num$ | fgrep -v 'guard variable'
 }}}

 That should print out the `long double
 boost::math::lanczos::lanczos17m64::lanczos_sum<long double>(long double
 const&)::num` symbol in each binary (and possibly other symbols).  Check
 that all occurrences of that symbol have the same symbol type (either "D"
 if C++98 mode or "S" if C++11 mode).  If not, `EXC_BAD_ACCESS` is likely
 to occur.

 Hope that helps,
 Kevin
