LI77136: SEGFAULTS WITH NON-XLF COMPILED MODULES

February 2013 Update for XL Fortran for Blue Gene/Q, V14.1

APAR status

• Closed as program error.

Error description

• The following test case uses the MPI module compiled by another
  compiler by accident.  The XLF compiler segfaults with internal
  compiler error after giving out the ligitimate 1514-220 error.
  
  bgxlf90_r -I./ sizeof.f90
  "sizeof.f90", line 3.9: 1514-220 (S) Module symbol file for
  module mpi is in a format not recognized by this compiler.
  Please compile the module with this compiler.
  ....
  1501-230 (S) Internal compiler error; please contact your
  Service Representative. For more information visit:

  1501-511  Compilation failed for file sizeof.f90.
  
  $cat sizeof.f90
    program test_sizeof
      use mpi
      integer :: x, size_x, ierr
      call MPI_INIT(ierr)
      call MPI_SIZEOF(x, size_x, ierr)
      call MPI_FINALIZE(ierr)
    end program test_sizeof
  

Local fix

• Include the correct module compiled by XLF. The error message
  is desired, but the se
  

Problem summary

• PROBLEM DESCRIPTION: XL Fortran issues internal compiler error
  when reading a module symbol file not created by XL Fortran.
  
  USERS AFFECTED: Users of XL Fortran 14.1 on all platforms
  

Problem conclusion

• The problem is fixed by doing the cleanup action before issuing
  the error message. Apply available service.
