APAR status

• Closed as program error.

Error description

• For a specific test case, the compiler abends in xlfcode when
  compiling using the following commands:
  xlf90_r -qfree=f90 -qsuffix=f=f90 -c *.f90
  
  The abend message that is seen is as follows:

• USERS AFFECTED:
  Users who has derived types that contains array component
  initialization in their modules may be affected by this issue.
  
  PROBLEM DESCRIPTION:
  The compiler produces an internal compiler error due to an
  initialization value being mis-placed in the wrong scope by the
  compiler.
