Hi,

it must be

struct Foo
{
  void resetFoo(const std::map<int,char>& foo = (std::map<int,char>()))
  {
  }
};

to disambiguate the syntax (declaration vs. definition; I believe that this is not a compiler issue;
in such cases often additional brackets help, since they are allowed around
expressions, but not around argument lists).
