    (Ref . UniSoft reply err.4.2.3.024)

    In the function aoctol() core dumps occur because overflow
    occurs if the value of len is greater than 10. This is a pity
    since it is called for the c_filesize field which is 11 long.
    The overflow can be avoided by changing the types of val &
    pow to unsigned long; the overflow still occurs but isn't
    raised for unsigned arithmetic.

    In addition it would be better if the continue within the
    loop was replaced by a break. Since the sole purpose of
    this is to skip leading spaces or NULLs if these occur one
    could presume that the string to interpret had finished.

    {The same bug occurs in both modules}
    Test Output
