According man of stroul

RETURN VALUE
       The strtoul() function returns either the result of the conversion or, if there was a leading minus sign, the negation of the result
       of the conversion represented as an unsigned value, unless the original (non-negated) value would overflow; in the latter case, str-
       toul() returns ULONG_MAX and sets the global variable errno to ERANGE.  Precisely the same holds  for  strtoull()  (with  ULLONG_MAX
       instead of ULONG_MAX).

ULONG_MAX is NOT LONG_MAX

So it must not work i guess (2.6.26 release).
Maybe in git it is fixed, dunno, i will check it now.
