APAR status

  • Closed as program error.

Error description

  • Error Message: Segmentation error
    .
    Stack Trace: OMR::ValuePropagation::findOutEdge
    TR::GlobalValuePropagation::processBlock
    ...
    .
    This issue only occurs on systems with transactional memory.
    

Local fix

  • The issue can be avoided by passing -Xjit:disableTLE. This
    option may degrade performance, but it can be limited to the
    problematic method.
    

Problem summary

  • In rare circumstances the JIT compiler could misconstrue the
    control flow effect of a transaction start operation, and
    attempt to find a nonexistent control flow edge.
    

Problem conclusion

  • The JIT compiler has been modified so that in these
    circumstances it only considers valid control flow edges.
    .

       8    SR4 FP10  (8.0.4.10)
