    Problem Text
    Error is generated in module ANSI.os/streamio/fflush/enospc.c, where
    at line 322 the following portion of code can be found:

    /*
    * Now complete writing of this block and try on the next one
    * This should not cause a failure because we have already
    * tried writing this block.
    */
    if (fwrite((void*)outstr, BUFSIZ-1, 1, fp) != 1) {
    err = errno;
    if (errno == ENOSPC) {
    xx_rpt(UNTESTED);
    in_rpt("out of space on fwrite");
    } else {
    xx_rpt(FAILURE);
    valrpt(1, 0, 0, err);
    }
    }
    else
    PATH_TRACE;

    Therefore this behaviour is accepted by the test which should exit with
    result "UNTESTED".
    Instead since this portion of code is in a loop that increases the
    variable "i" and since at the end of this routine there is the
    following instruction (line 353):

    PATH_XS_RPT(7+i);

    the path count is expexcted to be 8 but the actual value
    is 7 and test exits with result "UNRESOLVED".

    It seems that a "break" instruction is missing:

    if (fwrite((void*)outstr, BUFSIZ-1, 1, fp) != 1) {
    err = errno;
    if (errno == ENOSPC) {
    xx_rpt(UNTESTED);
    in_rpt("out of space on fwrite");
    } else {
    xx_rpt(FAILURE);
    valrpt(1, 0, 0, err);
    }
    >>>> break;
    }
    else
    PATH_TRACE;

    By the way, this "break" instruction is already present in another
    portion of code of the same module, which performs a similar control
    (line 249):


    if (fputc('a', fp) == EOF) {
    testfail++;
    if (errno == ENOSPC) {
    xx_rpt(UNTESTED);
    in_rpt("out of space on fputc");
    } else {
    xx_rpt(FAILURE);
    in_rpt("fputc failed");
    }
    break;
    }
