[Bug c++/18018] New: ICE on dubious extern declaration

[porten at kde dot org]

The "extern" declaration below probably doesn't make much sense. But when
putting this code into a C++ file (not C!)

  void foo()
  {
  }

  void bar()
  {
      extern void foo();
      foo();
  }

and compiling this with (the -g is important)

  gcc -c -g test.cpp

I get this error:
 
/tmp/test.cpp: In function `void bar()':
/tmp/test.cpp:9: internal compiler error: in gen_subprogram_die, at
dwarf2out.c:11183

gcc is from today's CVS HEAD. g++ -v gives:
