Hi,

Whilst updating SVN today I spotted a change to boost::lexical_cast,
https://svn.boost.org/trac/boost/changeset/71958, which introduces a
try { } catch(...) { } construction. I'm curious as to why this
catch-all is needed since it seems to be there to deal with
boost::numeric_cast exceptions and whether it could lead to a
std::bad_alloc being rethrown as a bad_lexical_cast.

Kind regards,
Jeroen Habraken
