axiom_node_to_string memory issues

[Brody Lodmell]

so the function
    AXIS2_EXTERN axis2_char_t *AXIS2_CALL
    axiom_node_to_string(
        axiom_node_t * om_node,
        const axutil_env_t * env);

returns a pointer to new data every time it is called.

how is this memory freed?

when I do a free() on the memory returned from this I get an error :
"Windows has triggered a breakpoint in appname.exe.

This may be due to a corruption of the heap, and indicates a bug in
appname.exe or any of the DLLs it has loaded."
