Does the problem ONLY arise with BSD?

Problems from bad logic design usually arise at once. In this case,
however, the problem arose after a certain period of time (in which I
never made the world, BTW). This isn't usually due to a design flaw in
the chip itself.

Hm, with me it's _ONLY_ cc that fails (i usually have my machine running
round-the-clock or at least 18 hours a day. Once I tried a make world
after 24 hours of working fine, and after half an hour or so it went
"tilt". In fact, I never had trouble with ANYTHING but cc, and ONLY when
in a "make-world" environment, and the machine NEVER crashed or so
except for other hardware mischief that I'm doing.

Now THAT looks like a happy prospect...

I am still in doubt whether it is ONLY the K6 or whatever. Might be
useful if I posted my configuration again:

ASUS TX97 Mainboard (said to support the K6 up to 233 MHz). Thermals
can't really be a problem, because if the processor
overheats, the board goes into "slow" mode. It never did.

AMD K6-200; 64 megs of RAM (4x16 MB PS/2 FPM 60ns, board configured for
60 ns FPM DRRAMs - should be OK, especially since i had used the same 64
megs in an AMD 486 at 160 MHz with extremely -well- experimental timings
and they worked fine)

The other junk, like Adaptec 2940U and HD and CDROM and graphics card
(MGA Mystique) shouldn't really matter.
