guththila parser fails attempting to deallocate unallocated cell if xml message contains more
than one namespace
----------------------------------------------------------------------------------------------------------------

                 Key: AXIS2C-812
                 URL: https://issues.apache.org/jira/browse/AXIS2C-812
             Project: Axis2-C
          Issue Type: Bug
          Components: guththila
    Affects Versions: Current (Nightly)
         Environment: Windows, Visual Studio 2005, guththila validating parser
            Reporter: Bill Mitchell


The guththila validating parser fails attempting to deallocate an unallocated cell if the
xml message constains more than one namespace.  The issue is that the validating parser allocates
one cell of memory to hold an array of namespaces, but that the code that frees the namespaces
believes that each array element is a separate cell.  Thus, if the array contains more than
one element, the free of the second element fails.  

One can see the problem when parsing a SOAP response message identifying two namespaces, e.g.,
one that begins:
<?xml version="1.0" encoding="UTF-8" ?> 
- <env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
- <env:Body>
...

This appears to be a problem introduced as part of fix AXIS2C-785 since 1.1.0 in the development
branch; in 1.1.0 the array was not freed at all.
