Local fix

  • No work arround
    

Problem summary

  • This crash was caused by a failure to allocate an object when we
    are not within a set_jmp region and therefore we simply return
    to the allocator with a NULL.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR1
    6.0.1 SR2
    WRT-V3 SR1
    .
    To avoid the arbitrary crash, we added code to recognize such
    case. It will print out an error message and then crash.
    Here is the message:
    "Out of native memory and no error handler is set"
    A full fix for the problem will be in dev.
