[Bug c++/23839] New: [4.1 Regression] ICE: expected var_decl, have parm_decl in cxx_mark_addressable, at cp/typeck.c:4343

[jsm28 at gcc dot gnu dot org]

class C
{
  int i;
public:
  C(int j) : i(j) { }
  operator int() { return i; }
};

C
f (register C x)
{
  return x + 31;
}

ICEs with current mainline (I suppose a regression, unless --enable-checking
compilers from previous release branches show the problem there too).

t1.cc: In function 'C f(C)':
t1.cc:12: internal compiler error: tree check: expected var_decl, have parm_decl
in cxx_mark_addressable, at cp/typeck.c:4343
Please submit a full bug report,
with preprocessed source if appropriate.
