--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
lsplit says it found a split point but then it does not do it without any info
on why not:
```
Analyzing # of iterations of loop 1
  exit condition [1, + , 1](no_overflow) < n_11(D)
  bounds on difference of bases: 0 ... 2147483646
  result:
    # of iterations (unsigned int) n_11(D) + 4294967295, bounded by 2147483646
Found potential split point: if (pos_13 <= m_14(D))
 { start_12(D) + I*1 } le_expr m_14(D)
```
