seg fault on DOMParser->parse()

[Dave Viner <dv...@yahoo-inc.com>]

I'm running into a problem trying to parse a string out of a memory
buffer.  I'm using xerces inside apache... 

I create a MemBufInputSource (exactly like the MemParse sample), then
reset my DOMParser, then pass the memory buffer to the parser

code:
   MemBufInputSource *memBufIS = new MemBufInputSource ( 
                                  (const XMLByte *)inString,
                                  strlen(inString),
                                  memBufId,
                                  false );
//
xmlDomParser->reset();
 xmlDomParser->parse( *memBufIS );


Inside the parse call, the server segfaults.  from gdb, it appears the
problem is:
#0  0x2836e7c4 in NameIdPool<DTDElementDecl>::removeAll (this=0x81b4520)
    at
/homes/dviner/xml/clean5/xerces-c-src1_3_0/include/util/NameIdPool.c:175
175                 delete curElem->fData;

Here are the surrounding lines from NameIdPool.c:

template <class TElem> void NameIdPool<TElem>::removeAll()
{
    // Clean up the buckets first
    for (unsigned int buckInd = 0; buckInd < fHashModulus; buckInd++)
    {
        NameIdPoolBucketElem<TElem>* curElem = fBucketList[buckInd];
        NameIdPoolBucketElem<TElem>* nextElem;
        while (curElem)
        {
            // Save the next element before we hose this one
            nextElem = curElem->fNext;

            delete curElem->fData;
            delete curElem;

            curElem = nextElem;
        }


Has anyone seen this problem?  It seem like the deleting the fData
element causes problems when the class is DTDElementDecl..

Suggestions on how to fix this?

thanks
dave
