---------------------------------------------------------------------
        Key: XERCESC-1245
    Summary: Memory Leak on Schema Validation Failure
       Type: Bug

     Status: Closed
   Priority: Major
 Resolution: FIXED

    Project: Xerces-C++
 Components: 
             Validating Parser (Schema) (Xerces 1.5 or up only)
   Versions:
             Nightly build (please specify the date)

Environment: Linux (Debian Sarge), i686, uniprocessor

Description:
I've got a test harness that loads a schema explicitly, then repeatedly
parses an XML document.

When the XML document is valid according to the schema, all is fine.
I can watch /proc/{pid}/status and the VmSize/VmData fields are steady.

But when it is not valid (ie parse reports a validation error to the
ErrorHandler, which throws an exception), a memory leak occurs. The
VmSize/VmData fields creeps steadily upward as repeated parse-fail cycles occur.

I will attach a test harness that demonstrates this problem.

This problem occurs on both the 2.5.0 release, and the nightly snapshot xml-xerces_20040725043234.
