JR31521: MEMORY LEAK IN TD CONNECTOR SETNATIVESTRING", AND "GETNATIVESTRING" FUNCTIONS

APAR status

• Closed as program error.

Error description

• There were 2 memory leak issues identified in the TD Connector
  since decimal 38 support was added via  125205
  
  
  1.found the heap size increases in 64 bytes while processing
  each record. These were for columns of type decimal.
  CC_PXAccessor::getBigDecimal() returns a pointer to a
  CC_BigDecimal object that is created in the function. This
  pointer is not saved under CC_PXAccessor and the object needs to
  be freed by its caller.  But the caller,
  CC_TeraDBStmtParamDecimal::writeBuffer(), did not do that. By
  ading the call of CC_BigDecimal::destroyInstance() to
  CC_TeraDBStmtParamDecimal::writeBuffer() and verified the heap
  size becomes constant and does not increase at all.
  
  2. There appears to be an memory leak in
  functions:
  "setNativeString", and "getNativeString" functions (in
  DAAPI-PX/fcl/PX_Accessor.cpp).
  
  Verified few TDCC jobs (both read & write), involving "charset
  conversion" and found that the issue is getting reproduced.
