    Problem Text

    There are mulitple problems for check_xloc.c. The fixes are provided
    below. The first problem is subscripting typo in init_stuff for
    nonspacing[2].string which should be nonspacing[1].string.

    The second problem is not allocating a shared memory object for
    an input buffer. A shared memory object needs to be allocated to
    'Rdata *rdata;' because test number 2 in check_xloc will use it
    (test2A() calls avsinit_xcurses(). avsinit_xcurses() calls
    basic_curses_init(). basic_curses_init() calls avsstart_term().
    avsstart_term() calls zerobuf(). zerobuf() accesses 'rdata'). The getbuf()
    functions is defined in SRC/LIB/capi_xcurses/out.c. A getbuf() function needs
    to be added to the init_stuff() function.

    The third problem is in both test cases 1 and 2. There is a for loop
    which at the beginning needs to initialize the buffer with a
    spacing string "strcpy(buf, spacing[i].string);". The loop then
    starts to concatentate non-spacing characters onto the buffer. The
    second time through the loop the buf "buffer" has not been initialized
    but still contains the original data for the previous test and will
    just have more incorrect data concatenated onto buf.

    The example of the problem would be through the loop (see code below)
    for j = 1 and k = 1 buf would look like

    spacing "1" non-spacing "4"

    the next time through the loop with j = 2 and k = 1

    spacing "1" non-spacing "4" non-spacing "4"

    The sequence is wrong. The strcpy(buf, spacing[i].string) function
    needs to be moved within the loop to initialize buf as described
    in the fix below both for test 1 and 2.

    Review Response
    We recommend this request be refused.

    Per the VSU User's Guide Section 8.3.5 check_xloc is "not a supported
    part of VSU and is not required for conformance". Thus a TSD is
    not appropriate as there are no branding implications here.
