seg fault

Hi All

I have written a small app to parse the xsd file ,

When I run the following xsd file , I am getting seg fault in libxml , and if I give backtrace, it loops indefinitely and prints the following message

 

#3221 0x4008a100 in xmlFARecurseDeterminism (ctxt=0x804eca0, state=0x804ea28, to=9, atom=0x0) at xmlregexp.c:2429

 

My xsd file contains the following .

 

<?xml version=&quot;1.0&quot; encoding="UTF-8" ?>

<xsd:schema xmlnssd="http://www.w3.org/2001/XMLSchema&quot;

 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; targetNamespace=&quot;http://www.pub.org"

 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp; &nbsp;  <xsd:element name=";Book1";  minOccurs="0&quot; />

 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; <xsd:sequence minOccurs=";1" maxOccurs="23&quot;>

 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp; &nbsp; <xsd:element name="Book12" minOccurs="0&quot; />

 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp; &nbsp; <xsd:sequence minOccurs=";1" maxOccurs="34&quot;>

 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp;  &lt;xsd:element name=";Book21&quot; minOccurs="0&quot; />

 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp;  &lt;xsd:element name=";Book22&quot; minOccurs="0&quot; />

 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp; &nbsp; </xsd:sequence>

 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; </xsd:sequence>

 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp;  &nbsp; &nbsp; &nbsp; &lt;xsd:element name=&quot;Book3&quot;  minOccurs="0&quot;/>

 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; &nbsp; &nbsp;   ;  <;/xsd:sequence>

 &nbsp; &nbsp; &nbsp; &nbsp;   ; &nbsp; &nbsp; </xsd:complexType&gt;

 &nbsp; &nbsp; &nbsp;  </xsd:element>

</xsd:schema>

 

My App is below

 

 

static int print_parseDS(xmlDocPtr doc){

 &nbsp;  xmlSchemaPtr schemaPtr = NULL;

 

 &nbsp;  xmlSchemaParserCtxtPtr ctxt = NULL ;

 &nbsp;  xmlSchemaValidCtxtPtr vxt = NULL;

 &nbsp;  ctxt  = xmlSchemaNewDocParserCtxt(doc);

 &nbsp;  schemaPtr = xmlSchemaParse(ctxt);

}

int main(int argc , char **argv) {

 

 &nbsp;  xmlDocPtr doc = NULL;

 

 &nbsp;  doc = xmlReadFile(argv[1] ,NULL,0);

 &nbsp;  print_parseDS(doc);

 &nbsp;  xmlFreeDoc(doc);

 &nbsp;  xmlCleanupParser();

 &nbsp;  return 0;

 

}
