Comment (by teor):

 You probably want `tor_parse_ulong()` here, because on i386, min is 1, and
 max is effectively `(long)UINT32_MAX`, which is -1.
 {{{
 long tor_parse_long(const char *s, int base, long min,
                     long max, int *ok, char **next);
 ...
 uint32_t version;
 ...
 version = (uint32_t) tor_parse_long(value, 10, 1, UINT32_MAX, NULL, NULL);
 }}}

 I think we could warn in the tor_parse_* functions when this happens, see
 #19063.
