Hi,
I have code that compiles OK with Gcc 4.4 but fails with 4.5 and I
cannot understand what the error I get from the compiler means. Maybe
someone here can give me a suggestion?
The error:

Snippets of relevant code (hopefully enough):
- the first snipped is how I declare the boost::fusion::map
- the second is how I use and where the error is (<--!!!!!!!!)
...
namespace UserCreator
{
struct objectId;
struct userId;
struct userName;
typedef boost::fusion::map
<
boost::fusion::pair< objectId, ObjectId >,
boost::fusion::pair< userId, int >,
boost::fusion::pair< userName, std::string >
UserArgs;
struct UserCreationArguments : public MOCFunctionParameter, public UserArgs
...
...
ModelObject* UserCreatorFunction::createObject( const MOCFunctionParameter* aMOCFunctionParameter /* = NULL */) const
{
...
if ( (arguments = dynamic_cast< UserCreator::UserCreationArguments* >(const_cast(aMOCFunctionParameter))) )
{
ObjectId& objectId = boost::fusion::at_key< UserCreator::objectId >(*arguments); <--!!!!!!!!
int& userId = boost::fusion::at_key< UserCreator::userId >(*arguments);
std::string& userName = boost::fusion::at_key< UserCreator::userName >(*arguments);
...
TIA
