           Summary: config/aarch64/cortex-a57-fma-steering.c:416: bad
                    statement order ?
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

  Target Milestone: ---

trunk/gcc/config/aarch64/cortex-a57-fma-steering.c:416]: (error) Dereferencing
'other_forest' after it is deallocated / released

Source code is

  delete other_forest;

  this->m_nb_nodes += other_forest->m_nb_nodes;

Somewhat unwise to delete something then use it.
Maybe other way around would be better.
