SSA form after inserting ASSERT_EXPRs
main ()
{
int i;
int c;
int b;
int D.1576;
:
c_4 = f ();
if (c_4 <= 0) goto ; else goto ;
:;
c_8 = ASSERT_EXPR ;
c_7 = -c_8;
goto ();

// this testcase fails also on amd64:
extern void abort (void);
int f ()
{
return -1;
}
int main ()
{
int b, c, i;
b = 0;
c = f ();
if (c <= 0)
{
c = -c;
for (i = 0;
