Are you sure your compiler supports exception handling in your setup? I'd  
try some simple exception hanlding program with the same compiler switches.
If you set breakpoint on 0040306B, does __cxa_throw resolve to 00000000 or  
you get there from inside __cxa_throw? If first, there something wrong  
with linking or compiler setup; if latter, something wrong with EH  
structures in generated code (either in boost or in your test program).  
Have you build boost yourelf? If not, maybe it is worthy to try to rebuild  
boost with the same compiler and try it. Make sure -fexceptions or  
whatevers it must be for mingw is used in build process.
