--- Comment #11 from Markus Trippelsdorf trippels at gcc dot gnu.org ---
This still happens with 4.9:
markus@x4 more % cat test.ii
namespace detail {
namespace indirect_traits {}
using namespace indirect_traits;
void fn1() {
using namespace detail;
}
}
markus@x4 more % g++ -ftime-report -c test.ii
test.ii: In function ‘void detail::fn1()’:
test.ii:5:17: internal compiler error: in timevar_start, at timevar.c:343
using namespace detail;

They changed the code to remove the crash. mike

Here is a small change to work around the crash :
namespace boost {
namespace detail { namespace variant {
struct variant_hasher: public //boost::
static_visitorstd::size_t {
template class T
std::size_t operator()(T const val) const {
//using namespace boost;
hashT hasher;
return hasher(val);
}
};
}}
}
It is the uneeded namespace usage that causes the problem.

I tried to reduce the input size but it is not producing any results.
namespace std {
typedef long unsigned int size_t;
};
namespace boost {
namespace detail {
struct is_static_visitor_tag { };
typedef void static_visitor_default_return;
}
template typename R = ::boost::detail::static_visitor_default_return
class static_visitor: public detail::is_static_visitor_tag {
public:
typedef R result_type;
protected:
static_visitor() { }~static_visitor() { }
};}
namespace boost
{
template class T struct hash;
template class T void hash_combine(std::size_t seed, T const v);
template class It std::size_t hash_range(It, It);
template class It void hash_range(std::size_t, It, It);
}
namespace boost {
namespace detail { namespace variant {
struct variant_hasher: public boost::static_visitorstd::size_t {
template class T
std::size_t operator()(T const val) const {
using namespace boost;
hashT hasher;
return hasher(val);
} };} }}
