[xml] xmlSchemaNewParserCtxt coredump

[Espen Ekeroth <espen ekeroth omxgroup com>]

Hi, we are having a problem with the
xmlSchemaNewParserCtxt function. Some of our schemas are creating coredumps
in the xmlSchemaNewParserCtxt function, and some are not. Could this be
a problem in the schema?


int mcxml_ValidateAgainstSchema(XML_SETTINGS
settings, xmlDocPtr doc, char *caller, 
         
               
      char *schema_file, MCXML_STATUS *status) 
{
  xmlSchemaPtr schema = NULL;
  xmlSchemaParserCtxtPtr ctxt;
  
  char *schema_file_fp = mcxml_GetSchemaWithLocation(settings,
schema_file, status);

  if (status->status == XML_OK)
{
    ctxt = xmlSchemaNewParserCtxt(schema_file_fp);

              <xs:element

      </xs:sequence>
        </xs:complexType>
</xs:schema>


I do see that there are some differences
in how the schemas are written, but I do not know that much about xml schemas.
Could anybody tell me what to look for?
