This very simple code:
#include
#include <string>
const boost::any getBoolVal()
{
return false;
}
int main()
{
boost::any vals[] = {1.0, std::string("1m"), getBoolVal()};
}
When built using Visual C++ 2010, it will run into a infinite loop:

Sorry I don't know enough of the c++ standard to figure out whether it is
because of Visual C++ or it is because of boost. But I think it is worth to
raise it to the experts out here.
