Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 5 and later        *
  *                 releases compiling with TEST(NOSEPARATE)     *
  *                 or equivalent options and running            *
  *                 programs which abend or generate             *
  *                 a CEEDUMP.                                   *
  ****************************************************************
  * PROBLEM DESCRIPTION: When COBOL fails to initialize DWARF    *
  *                      information for unknown reasons,        *
  *                      it might cause a possible memory leak.  *
  ****************************************************************
  * RECOMMENDATION: Install the provided PTF.                    *
  ****************************************************************
  When a program abends or a CEEDUMP is generated, various
  data is extracted from DWARF information which is embedded in
  program objects.
  
  When COBOL Runtime fails to initialize the DWARF information
  for unknown reasons, internal clean-up logic was inadvertently
  bypassed potentially causing a memory leak.

Problem conclusion

• COBOL Runtime logic has been corrected to call the internal
  clean-up routine 'dwarf_finish' when DWARF initialization fails.
