SY> You're welcome. Not building 21.5 too often these days huh? SY> :-P Every day or so, why? I'm running _with_ my patch (third version, actually)---doing this wrong results in crashes, that's why Mike's original patch was backed out, and I abandoned my first two tries. These test failures do not change the meaning of correctly written programs (as I understand it, and assuming you have infinite memory); it's a performance issue (allowing some stuff that is semantically garbage to get collected although there are still "weak" pointers to it around). SY> BTW, just curious as to why the C tests aren't run if error SY> checking is turned off? Dunno. I suspect a lot of them depend on side effects of the error checking versions of the macros or something like that. -- Institute of Policy and Planning Sciences http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
