Error Message: N/A . Stack Trace: N/A .
Local fix
This issue can be avoided using the -Xjit:disableLoopVersioner option. This option may cause a noticeable performance degradation.
Problem summary
The JIT compiler was performing a loop optimization that resulted in an incorrect branch condition being generated in compiled code, resulting in the unintended execution of either a fast or slow loop.
Problem conclusion
This defect will be fixed in: 7.0.0 SR1 6.0.1 SR2 . The JIT compiler has been amended to prevent this incorrect behaviour.
Temporary fix
