PH66219: INTERNAL ERROR WHILE COMPILING PROGRAM: FAILED ASSERTION ON ./SEQUENTIALSTORESIMPLIFIER.CPP:3942

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The compiler's internal state is incorrect while performing Loop
  Inversion. Loop Inversion uses integer loop control variables
  (4-byte long); however, some loops are controlled by smaller
  induction variables.
  
  
  When inverting a loop, the compiler assigns the "final value"
  to the induction variable, which may involve converting an
  integer data type to the shorter data type used in the program.
  This conversion was not consistently implemented,
  resulting in inconsistencies in the program's intermediate
  representation.
  

Local fix

• Extend the loop variable to a minimum length of 5 digits /
  Change the data item to be PIC S9(5)/9(5) or larger
