  ****************************************************************
  When a program has many ODO (Occurs Depending On) data items
  defined, each reference to such data items causes the code
  generator to try to bring the calculation routines inline.
  Each of these inline attempts takes more memory, so when a
  program that has over 400 of these inline sites, the compiler
  step can run out of memory.
  

Problem conclusion

• The compiler code generator was changed to use less memory for
  each inlining attempt.  In addition, a mechanism was added to
  back off on optimizations when they run the risk of using too
  much memory and jeopardizing an optimized compile.
