Error description

  • Error Message: SIGSEGV received in libjitc.so
    .
    Stack Trace: Few top frames are:
    
    fi_init() at

    java.lang.Throwable.fillInStackTrace
    (Exception.java)::java.lang.Exception.<init>
    .
    The crash occurs during Frame Traversal when JVMPI agent is
    used.
    

Local fix

  • N/A
    

Problem summary

  • Crash in fi_init during initialization of frame traversal. Crash
    in fi_prev when traversing the stack in response to exception
    thrown by jvmpi agent which gets invoked during jit compilation
    of a method.
    

Problem conclusion

  • This defect will be fixed in:
    1.4.2 SR13 FP5 (Linux IA32)
    .
    Introduce additional checks in fi_init to prevent the particular
    code flow which resulted in crash
    .
    To obtain the fix:
    Install build 20100115 or later
    

Temporary fix
