[Bug c++/27129] [4.1/4.2 Regression] ICE in get_expr_operands

IMO, the line defining c should trigger an error message because it needs to
use c before creating the variable, or else undefined behaviour occurs.
This message could be:
 error: ‘c’ was not declared in this scope
or:
 error: 'c' is used uninitialized

Consider:

$ more test.cc
#include <stdio.h>

static const float f = 1 - a;

int main(void)
{
    printf("%f\n", f);

    return 0;
}

$ g++ -Wall  -O2 -o test  test.cc
test.cc:3: error: &#8216;a&#8217; was not declared in this scope

$ more test1.cc
#include <stdio.h>

static const float f = 1 - f;

int main(void)
{
    printf("%f\n", f);

    return 0;
}

$ g++ -Wall  -O2 -o test1  test1.cc
$

There should be an error message there as well.
