* [Bug middle-end/17525] New: 4.0: ICE in emit_move_insn (non-BLKmode arg)

g++ gives an ICE on the source below:

$ ./cc1plus -quiet x.cc
x.cc: In member function `B& B::operator=(const B&)':
x.cc:14: internal compiler error: in emit_move_insn, at expr.c:2485
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
$

Here's where it's crashing:

2484      gcc_assert (mode != BLKmode
2485                  && (GET_MODE (y) == mode || GET_MODE (y) == VOIDmode));
2486

because here mode == BLKmode.

(gdb) call debug_rtx(x)
(reg:BLK 62)
(gdb) call debug_rtx(y)
(mem/s:BLK (reg:SI 59 [ D.1610 ]) [0 S4 A32])

Environment:
System: Linux karma 2.6.8.1 #20 Mon Sep 13 23:48:47 EDT 2004 i686 i686 i386 GNU/Linux

How-To-Repeat:

Compile the following (optimization not required):

--------------------------------------------------
struct A

  ~A();
  int a;
};

struct B : public A
{

};

void run (B& b, B& b1)

Confirmed.

Phil's regression hunter says:
: Search converges between 2004-08-30-trunk (#529) and 2004-08-31-trunk (#530).

Richard, it looks as if your patch
http://gcc.gnu.org/ml/gcc-cvs/2004-08/msg01565.html
is responsible for the regression.

Could you please have a look?

I want to say this is a front-end bug (or gimplifer one) because the assignment:
  this->D.1585 = *D.1606;
still has a type of the struct which is BLK_MODE.

------- Additional Comments From rth at gcc dot gnu dot org  2004-09-24 20:38 -------
Problem here is that we've got 

basetype
 <record_type 0xb71eac3c A addressable type_1 type_2 type_4 type_5 BLK
CLASSTYPE_AS_BASE (basetype)
 <record_type 0xb71ed740 SI

Which means that the base class access via "this->D1234" has a different
mode than accessing something of class A via a different method.
