IT15372: MEMORY LEAK IN XML4C WHEN USING ITX/WTX NODES

APAR status

• Closed as program error.

Error description

• When using ITX/WTX nodes in an IIB flow the ITX/WTX libraries
  use the version of XML4C shipped with IIB. The WTX/ITX team has
  identified a memory leak which is resolved under ITX/WTX APAR
  PI62025. The IIB copy of the XML4C libraries also needs to be
  updated to contain this defect fix.
  
  The issue occurs when validating an element in a WTX/ITX node
  where the element has minOccurs=0 and maxOccurs equal to any
  value other than 0 or 1 and when this element is of type "Leaf".
  The symptom is a 200 byte leak per element of this type
  processed.
