APAR status

  • Closed as program error.

Error description

  • Error Message: N/A
    .
    Stack Trace: N/A
    .
    the typical symptom is that a run involving DLT is not
    successful (deadloop, crash or incorrect result).
    

Local fix

  • -Xjit:disableDynamicLoopTransfer
    

Problem summary

  • Program involving DLT deadloops/crashes/results in wrongly.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR4
    6.0.1 SR5
    6.0.0 SR13
    .
    When outer and inner loops are identified, we test with one
    condition. When control is steered to form canonical loop or
    create irregular regions, we test for a different condition.
    That can cause more entries created than identified, causing
    memory overflow.
    

Temporary fix

  • N/A
