Local fix
-Xjit:disableGlobalVP As with any option that disables an optimization, this can cause the jit compiler to generate slower code.
Problem summary
The jit compiler's Global Value Propagation optimization was made more aggressive in an attempt to improve the performance of the generated code, but the changes made were not correct in all cases.
Problem conclusion
This defect will be fixed in: 7.0.0 SR4 6.0.1 SR5 . The new Global Value Propagation logic was disabled, thereby restoring the jit compiler's older, correct behaviour.
Temporary fix
