PH09809: FABLDIAG CAUSES ABEND0C4

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• FABLDIAG module retrieves APAR number from LIU load module
  library.  FABLDIAG calculates the region to search APAR number
  in the LIU load module library but it calculates wrong region
  when some conditions meet.  This APAR fix the problem.

  This APAR fixes the Diagnostics Aid (FABLDIAG) not to cause
  ABENDS0C4 when it processes the LIU load module to generate the
  Load Module APAR Status report.
  
  It is caused when the FABLDIAG processes the LIU load module
  which CSECT has no APAR information such as APAR number and
  APAR Fix-date.
  
  Some LIU load modules have no APAR information in their CSECT.
  FABLDIAG checks whether LIU load module has an APAR information
  or not. It compares the APAR information section size to the
  CSECT size to check whether the APAR information is in the
  CSECT or not.
  
  If some of the LIU load module has a small APAR information
  section size, FABLDIAG calculates the address of the APAR
  number or Fix-date out of the CSECT. If the section size is too
  small, FABLDIAG should skip processing the module and confirm it
  does not have APAR information section. ABENDS caused by this
  wrong logic.
  
  FABLDIAG is fixed to check if the APAR information section size
  is not too small to obtain right APAR number and Fix-date.
