Error description

• When compiling large Fortran applications with DWARF debug
  information via the -qdbgfmt=dwarf option, different compile
  failures are seen.
  
  
     === EXAMPLES ===
  
  1501-230 Internal compiler error (bolt); please contact your
  Service Representative.
  1501-511  Compilation failed for file test.f.
  
  
  "test.f", 1500-053 (S) Too much initialized data.
  1501-511  Compilation failed for file test.f.
  
  "test.f", 1500-004 (U) INTERNAL COMPILER ERROR while
  compiling ----.  Compilation ended.  Contact your Service

  1501-511  Compilation failed for file test.f.
  

Local fix

• - Reduce application source size
  - Do not use DWARF debug info
  

Problem summary

• PROBLEM DESCRIPTION:
  Compiling large Fortran source in 32-bit mode with DWARF debug
  information resulting in internal compiler errors.  64-bit mode
  compiles without issue.
  
  USERS AFFECTED:
  Those compiling large Fortran applications in 32-bit mode with
  -qdbgfmt=dwarf
  

Problem conclusion

• The internal compiler issue was resolved and 32-bit compiles
  will now be successful.
  

Temporary fix
