[TRAFODION-2727] Memory leak in the compiler part of the code in Trafâ¦
â¦odion
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.
