 works, but if you strip it with just 'strip', it crashes?

 Correct.

 Bus error.

 > Does the application actually work if stripped with "strip -S -x"?

 Well, the application above doesn't actually do much!  But it doesn't
 crash.  If I add in a few headers and send the cm matrix to std::cout,
 everything works as expected:

 {{{
 #include <boost/thread.hpp>
 #include <boost/numeric/ublas/matrix_sparse.hpp>
 #include <boost/numeric/ublas/io.hpp>
 #include <iostream>

 int main (int argc, char * argv[])
 {
   boost::numeric::ublas::coordinate_matrix<double> cm;
   cm.resize(3, 3, false);
   cm(0, 0) = 1;
   cm(1, 1) = 2;
   cm(2, 2) = 3;
   std::cout << cm << std::endl;
   return 0;
 }
 }}}

 In the above, if you compile and run with bjam debug and strip (no
 options), it crashes before giving any output.  (If you comment out
 #include boost/thread.hpp, it works as expected.)
