I know this is not new, but I've just bumped into it....

This code

#include <iostream>
#include <boost/lexical_cast.hpp>

int main(int argc, char* argv[])
{
try
{
    ulong u = boost::lexical_cast<ulong>("-1");
    cout<<"Conversion"<
}
catch(const std::exception&)
{
    cout<<"Exception"<
}
}

Silently returns ULONG_MAX under MSVC7, though not under GCC. It's
an accuate reflection of how the underlying C library handles it, but do we want
to propogate this strangeness?
