The testcase was "broken" by Jan's big patch on Nov 3
     https://gcc.gnu.org/ml/gcc-patches/2017-11/msg00104.html
It didn't seem useful to look into that, so I tried running 
multidelta/creduce on the elfutils sources, and managed to get a small 
testcase that still fails with mainline.  I then fixed it to get rid of 
the warnings.

#include <stdlib.h>
extern int c (void);
int
a(int b) {
   if (c())
     abort();
}

There is no guarantee that this testcase will still show the problem in 
the future, but it seems good enough for now.

OK with this testcase.  And with your testcase too if you think that 
still has value.
