IV72272: SEGMENTATION ERROR VALUE PROPAGATION
Closed as program error.
Error Message: Unhandled exceptionType=Segmentation error vmState=0x00051cff . Stack Trace: The stack trace in gdb will most likely contain the following methods:._ZN15TR_VPConstraint9intersectEPS_P19TR_ValuePropagatio n ()._ZN19TR_ValuePropagation19addConstraintToListEP7TR_NodeiiP15T R_VPConstraintP12TR_HedgeTreeINS_15ValueConstraintEEb ()._ZN19TR_ValuePropagation18addBlockConstraintEP7TR_NodeP15TR_V PConstraintS1_b ()._ZN19TR_ValuePropagation13getConstraintEP7TR_NodeRbS1_ ()._Z12findConstantP19TR_ValuePropagationP7TR_Node () . N/A
-Xjit:disableGlobalValuePropagation,disableLocalValuePropagation will prevent the crash. Any resulting performance degradation can be mitigated by limiting this option to the method being compiled at the time of the crash.
The Value Propagation optimization attempted to obtain type information for a certain expression in the program, and this required the optimization to obtain a lock. If the optimization was unable to acquire the lock immediately (which could occur during garbage collection), it chose to continue without the desired type information, but subsequent processing was unable to proceed without the information, and crashed.
The optimization was changed to wait for the lock, thereby ensuring that it always obtains the desired type information. . This APAR will be fixed in the following Java Releases: 7 SR9 (220.127.116.11) 7 R1 SR3 (18.104.22.168) 6 R1 SR8 FP4 (22.214.171.124) .
