This type ought to inherit from boost::bad_lexical_cast, so you should be able to catch bad_lexical_cast.

What seems confusing to me is that the lexical_cast docs do mention "catch (bad_lexical_cast &)" as correct code (http://www.boost.org/doc/libs/1_39_0/libs/conversion/lexical_cast.htm). The solution that worked for me was to catch boost::exception instead.

Am I missing something here? I consulted the documentation, but still have no answer. It also seems that I am not alone with this problem;

http://www.nabble.com/Porting-from-boost_1_33-to-boost_1_36-exception-td1970... and http://archives.free.net.ph/message/20090715.183116.374b4777.en.html

at least indicate this for me.

It works for me with msvc 9.0. Do you have a test case? #include <boost/lexical_cast.hpp> #include <iostream> int main() { try { int i = boost::lexical_cast<int>("123ee"); } catch(boost::bad_lexical_cast&) { std::cout << "okay" << std::endl; } catch(...) { std::cout << "???" << std::endl; } } In Christ, Steven Watanabe
