[xml] libxml2 : xmlFreeTextReader crashes

[Suneel Mekala <sun 1601 gmail com>]

Dear all,

I am using libxml2 (libxml2-2.7.6-1.fc10.x86_64 )
I get crash when I call xmlFreeTextReader after the XMl file is processed. 
Following is the sample code that I am using:

xmlTextPointer = xmlReaderForMemory(buffer, strlen(buffer), "somthing.xml", NULL, 0);
while(errorCode == 1)
  {
    printf("Name : %s\n",xmlTextReaderConstName(xmlTextPointer));

    errorCode = xmlTextReaderRead(xmlTextPointer);
  }
xmlFreeTextReader(xmlTextPointer);


The buffer contains valid XML data, as it parses complete buffer and prints all the names (nodes)
and when xmlFreeTextReader is called it crashes 

Following is the backtrace:
