APAR status

  • Closed as program error.

Error description

  • Error Message: N/A
.
Stack Trace: N/A
.

Local fix

  • -Xjit:disableDynamicLoopTransfer

Problem summary

  • Summary is that it is an issue with DLT (dynamic loop transfer)
that is fairly unlikely. One would need aliasing sets to be
pruned based on IL peeking (only happened at higher opt levels)
and such a call would have to be in the first block, and then
finally some DLT buffer loads would need to be moved past such a
call.

Problem conclusion

  • This defect will be fixed in:
7.0.0 SR1
6.0.0 SR11
6.0.1 SR2
.
JIT was fixed.
