            Bug ID: 58399
           Summary: explicit constructor called implicitly with empty
                    init-list
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: f.heckenbach@fh-soft.de

I think the following test should not compile, where an a object is implicitly
constructed when calling foo() using its explicit constructor.

struct a
{
  explicit a () { }
};

void foo (a)
{
}

int main ()
{
  foo ({ });
}
