963,typeof: nested types of BOOST_TYPEOF'ed type don't work on gcc 3.4.5 in native mode,snaury@…,Peder Holt,"Example:

{{{
#include <boost/typeof/typeof.hpp>
#include <boost/typeof/std/vector.hpp>
BOOST_TYPEOF_REGISTER_TYPE(std::vector<int>::iterator)
BOOST_TYPEOF_REGISTER_TYPE(std::vector<int>::const_iterator)

int main(int argc, char** argv)
{
    std::vector<int> v;
    BOOST_TYPEOF(v)::iterator i = v.begin();
    return 0;
}
}}}

Results in an error on gcc-3.4.5

{{{
1.cpp:9: error: expected initializer before ""i""
}}}

This is because apparently you can't do typeof(v)::type in gcc 3.4.5. Workaround is very simple, but maybe it's better if this is implemented in boost.typeof itself:

{{{
#include <boost/typeof/typeof.hpp>
#include <boost/typeof/std/vector.hpp>
BOOST_TYPEOF_REGISTER_TYPE(std::vector<int>::iterator)
BOOST_TYPEOF_REGISTER_TYPE(std::vector<int>::const_iterator)

template<typename T> struct ut_type_mirror { typedef T type; };
#define UT_TYPEOF(v) ut_type_mirror<BOOST_TYPEOF(v)>::type

int main(int argc, char** argv)
{
    std::vector<int> v;
    UT_TYPEOF(v)::iterator i = v.begin();
    return 0;
}
