[Bug fortran/15955] New: ICE in make_decl_rtl, at varasm.c

[Mart dot Rentmeester at sci dot kun dot nl]

This piece of (valid) code generates an ICE.
When the private attribute to the module is
removed a different error occurs (which is
also submitted as a bug).

gcc 3.4.0 is also affected, here's an alternative snippet:

  struct S
  {
    double d;
    int i;
  };

  S f ()
  {
    double a = 0.0;
    S b = { a, 0 };
    return b;
  }

  void g () { f(); }


  $ g++ -O7 -c t.cpp

gccbugs@contacts.eelis.net, your bug is PR15461 and not this one, this is a bug in the new fortran 
front-end.

Closing as a dup of bug 16609 which has a small example.
