    It was found that CmpMessageReplyCode was not getting deleted at all times.
    But, the handling of CmpMessageDescribe messages in the compiler code has some
    mysterious issue that corrupts the memory causing unpredictable behavior when
    CmpMessageReplyCode is deleted.  To circumvent this problem, the CmpStatement heap
    is used for embedded compiler to allocate CmpMessageReplyCode and the Context heap
    is used in case of standalone compiler. The handling of CmpMessageDescribe will
    continue to leak memory in standalone compiler.
