Hi all, 

I'm getting an error using Boost.Exception V1.44 when trying to 
compile a file which #include's <boost/exception_ptr.hpp> with 
a QNX 6.5.0 toolchain (gcc 4.4.2):

Is there an explicit destructor definition missing in the derived 
class boost::exception_detail::bad_alloc_ ?

Thanks for your help.
