IJ36573: With -qlanglvl=nonewexpn (default), the allocation will not null-check the new allocation

APAR status

• Closed as program error.

Error description

• With -qlanglvl=nonewexpn (default), the
  compiler will not null-check the new
  allocation, which may return 0 upon
  failure.
  

Local fix

• -qchecknew is not documented for XLC++ for AIX but does force
  the null check.
  

Problem summary

• USERS AFFECTED:
  Users who compile with xlC might be affected by this issue.
  
  PROBLEM DESCRIPTION:
  With -qlanglvl=nonewexpn (default), the compiler will not
  null-check the new allocation, which may return 0 upon failure.
  

Problem conclusion

• The compiler knows the global non placement new operator may
  return null with -qlanglvl=nonewexpn. So it now inserts the
  null check without the user needing to specify an option to
  force it so.
  

Temporary fix
