ICE size_binop, at fold-const.c:1914 with gcc 3.0 i686-pc-linux-gnu

["John David Anglin" <dave at hiauly1 dot hia dot nrc dot ca>]

In looking at the failure of gcc.c-torture/compile/20010605-1.c on the
PA, I wondered if a similar failure would occur using a `block' argument:

# 1 "/xxx/gnu/gcc-3.1/gcc/testsuite/gcc.c-torture/compile/20010810-1.c"
int
main (int argc, char **argv)
{
  int size = 10;

  typedef struct {
    char val[size];
  } block;
  int retframe_block (b)
      block b;
    {
      return sizeof (b);
    }

  return 0;
}

This results in the following ICE on i686 linux:

dave@hiamlx:~/gcc_test > gcc -S xxx.i
/xxx/gnu/gcc-3.1/gcc/testsuite/gcc.c-torture/compile/20010810-1.c: In function `retframe_block':
/xxx/gnu/gcc-3.1/gcc/testsuite/gcc.c-torture/compile/20010810-1.c:13: Internal compiler error in size_binop, at fold-const.c:1914

Does the test look valid?
