PI76749: IGZEINI1+B0C abend0c4 checking entry point eyecatcher via CLLE of DELETE'd module

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• During initialization of a COBOL module, the run-time examines
  the modules on the COBOL load list entry (CLLE) chain. If the
  module associated with a CLLE has been unloaded without the
  run-time's knowledge, for example with a DELETE SVC from
  assembler code, the CLLE may point into unmapped storage,
  leading to an abend0c4.
  

Local fix

• Use CEEFETCH/CEERELES macros rather than LOAD/DELETE.

  Protect the access of the entry point in the internal control

Problem conclusion

• The COBOL runtime as been corrected to avoid the S0C4 abend.
