Bug ID: 88165
   Summary: error: default member initializer for 'A::B::m'
required before the end of its enclosing class
   Product: gcc
   Version: 8.2.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
  Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

The following compiles with MSVC2017 and not with gcc8.2. This bug was reported
first on stackoverflow
(https://stackoverflow.com/questions/53408962/try-to-understand-compiler-error-message-default-member-initializer-required-be)

minimum code example:
-prog.cc-
#include 
class A
{
   public:
  class B
  {
 public:
explicit B() = default;
~B() = default;

 private:
double m = std::numeric_limits::max();
  };

   void f(double d, const B &b = B{}) {}
};

int main()
{
   A a{};
   a.f(0.);
}

compile command:
g++ prog.cc -std=c++17 

error message:
prog.cc:15:36: error: default member initializer for 'A::B::m' required before
the end of its enclosing class
void f(double d, const B &b = B{}) {}
^
prog.cc:12:22: note: defined here
 double m = std::numeric_limits::max();
