    Problem Text

    An identical error exists in y0 test 11.

    The fault in this case is caused by a floating point overflow
    in the test suite. The modus operandi of the suite is to
    call the funciton under test and then to call its own function
    and to compare the results.

    In these two cases the test is checking overflow condition handling
    within the y0() library function. Unfortunately although
    our code returns -HUGE_VAL & sets errno to ERANGE the test still
    calls its own function which promptly overflows and core-dumps.

    The test code ought to skip the call of its own function in these
    two tests if overflow has been indicated by the library function
    to avoid this case.
    Test Output

    /tset/XOPEN.os/maths/y0/T.y0 10 Unresolved

    child process was terminated by signal 8 (SIGFPE)
