PH56949: At OPT(>0) IGYCB7104-U Internal error ... Failed assertion on ... /il/Node.hpp:1368 with _optAttributes is NULL!

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• With optimization, for a program RETURNING a datatype that can't
  be returned in a register, typically something not a simple
  binary or floating point type, and ending with a STOP RUN rather
  than a GOBACK, the compiler fails:
  
  IGYCB7104-U  Internal error while compiling program {program}.
               Failed assertion on ... /il/Node.hpp:1368.
               Compilation terminated.
  

Local fix

• Use a GOBACK

  ****************************************************************
  The compiler's internal state may become inaccurate when
  compiling programs at OPT(1|2) that return a data item that
  isn't binary or floating point and have a STOP RUN statement.
  When the compiler detects that its internal state is
  inaccurate, it abends.
  

Problem conclusion

• The compiler was fixed to update its internal state correctly.
  

Temporary fix
