    Problem Summary TSD4U.00298 When instr() is defined as a macro the test may fail due to a buffer overrun
    Problem Text
    The following is part of the file "L.xcurses4" in tset/CAPI.hdr/misc/xcurses4/
    that corresponds to the test case 90:

    .
    .
    .
    static void test387A(void)
    {
    #if 1
    #ifdef instr
    int ret;
    int arg1 = 0;
    char * ret1;
    char * str="test";
    pid_t pid;
    #endif
    #endif


    #if 0
    puts("ERROR: Header file curses.h not found");
    result_flags |= 1; /* FAIL */
    #else
    #ifndef instr
    result_flags |= (1<<4); /* UNSUP */
    #else
    alarm(5*SPEEDFACTOR);
    s2 = 0;
    infd = fopen("/dev/tty", "r");
    outfd = fopen("/dev/tty", "w");
    if (infd == 0 || outfd == 0) {
    perror("could not open /dev/tty");
    result_flags |= 1; /* FAIL */
    s2 = -1;
    }
    else if (newterm(getenv("TERM"), outfd, infd) == 0) {
    puts("newterm() failed");
    result_flags |= 1; /* FAIL */
    s2 = -1;
    }
    if (s2 == -1)
    return;

    (void) instr(ret1 = (arg1++, str));
    .
    .
    .

    The function instr() places a string of characters from the current
    window into the array pointed to by 'str', starting at the current
    position and ending at the end of the line. In this case, it starts
    at the beginging of the line and ends at the end of the line. And
    each line has 80 columns. Thefore, the above instr() function will
    place at least 80 bytes into 'str'. However, this program has
    allocated only (4+1) bytes for 'str' (actually it has initialized
    'str' with "test".) As a result, the program causes buffer overrun
    and the test result gets unreliable.

    Test Description:
    Base Conditional Conformance
    If the macro int instr(char *str) is declared in curses.h it shall
    evaluate its argument exactly once, fully protected by parentheses
    where necessary, protect its return value with parentheses, and return
    a value of the correct type.
