You are right, this is not a dup. original testcase still fails even after bug
24141 fixed:
void abort (void);
int f (int a, int b)
{
if (a == 1)
a = 0;
if (b == 0)
a = 1;
if (a != 0)
return 0;
return 1;
}
int main (void)
{
if (f (1, 1) != 1)
abort ();
return 0;
}

I'm not so sure that this is a dup. Bug 24141 is a wrong-code problem,
and this is an ICE. Just the fact that the same test case triggers both
bugs doesn't mean they are the same problem.
