APAR status
Closed as program error.
Error description
Error Message: Unhandled exception Type=Segmentation error vmState=0x000529ff (In 5.0 and 6.0, the precise vmState number might be slightly different.) . Stack Trace: N/A .
Local fix
-Xjit:disableLoopCanonicalization
Problem summary
The Loop Canonicalization optimization neglected to consider one possible sequence of code in a method. When it encountered that sequence, the optimization transformed the method in an incorrect way, leaving the JIT compiler's internal data structures in an incorrect state, which lead to a crash during a later optimization.
Problem conclusion
This defect will be fixed in: 6.0.0 SR15 FP1 6.0.1 SR7 7.0.0 SR6 5.0.0 SR16 FP5 . The Loop Canonicalization optimization has been fixed to support the neglected code sequence.
Temporary fix
