Could you send me the the following files... (1) code that works properly, (2) code that fails, (3) the debug log for each of these running on your machine, (4) the version of the operating system running in domU, and (5) your xenaccess.conf file? Without these details it's basically impossible to see what is happening on your system because this function is working fine on my test system at the moment.

It should go to the UNICODE_STRING type inside the structure, parse this struct, and then follow the pointer to the string. Instead, it is just jumping past the end of the struct and assuming that the string will be there (which isn't always the case).
