PI51187: COBOL V5 MODULE SIZE WITH OPT(2) MUCH LARGER THAN V4.2 COMPILED MODULE FOR SOME MODULES

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• If there are very many opportunities for inlining, the inlined
  code can cause the module size to become quite large.
  

Local fix

• Using TEST(EJPD) will reduce inlining, though at the cost of
  additional global optimization.
