APAR status

  • Closed as program error.

Error description

  • The compiler produces an internal compiler error when using the
-v option; and hangs without -v for a large test case.

Local fix

  • N/A

Problem summary

  • USERS AFFECTED:
Users with vector asm code are affected by this issue.

PROBLEM DESCRIPTION:
The compiler produces an internal compiiler error in the
backend due to a missing store in the intermediate file
generated from the compiler frontend.

Problem conclusion

  • The compiler now correctly inserts the missing store in the
intermediate file. This additional store ensures that
uninitialized variables are not being loaded.

Temporary fix
