>Organization:
>Environment:
Linux i686, kernel 2.4.5
>Description:
The code attached compiled with g++ bug.C gives:
bug.C: In function `int main()':
bug.C:23: uninitialized const member `components::m_g'


 
>How-To-Repeat:
g++ bug.C

Where bug.C contains:

class hgraph_base {
  public:
  int foo;
};

class Hnode;


class components {

  hgraph_base& m_g;
  int Hnode::* m_node_nr;

public:
  inline components(hgraph_base& pg) : m_g (pg) {
  }
};

int main () {
  
  hgraph_base base;
  
  components bi(base);
  
  return 0;
}
>Fix:
change hgraph_base& into hgraph_base* (and adapt the rest of the program) or comment out the line 
int Hnode::* m_node_nr;
(this is - of course - not really a fix, but might hint at the problem)
