Well, it's a long shot, but I can offer a -possible- explanation from an
experience I had with the same errors last weekend.
I have an Intel DX2-66 that I recently overclocked to 80MHz (no comments,
please, overclocking isn't the issue here), and it ran fine under
MS-Windows, DOS, and Linux/X. I even did some CPU-intensive stuff like
an 11-hour ray-trace of an F-18 under POVRay for Linux to make sure that
everything worked OK.
I picked up 1.1.61, and tried to compile it, and got several errors. The
only problem was, the errors weren't consistent, and they weren't always
reproducible; sometimes gcc would barf at one spot, and I'd simply
type "make zImage" again, and it would make it past that point (only to
barf at another point later on.)
The problem, I discovered, was in my BIOS chipset settings. I have a
relatively slow 256K of cache (20ns), yet I had my cache timings set to
maximum performance settings (2-1-1). This worked fine running at 66MHz,
and -seemed- to work fine at 80MHz. Well, I used more conservative
settings for my cache, and that solved the problem with only a -very-
minor hit in performance. So it turned out that the problem only
surfaced when doing a VERY processor/memory intensive task, like
compiling the kernel.
The reason I think this may be your problem is that, from what you said,
you have a true DX-50 (50MHz external, 50 internal) rather than a DX2-50
(25MHz external, 50MHz internal). If that's the case, that means your
external (L2) cache is running at 50MHz. Normally this shouldn't cause a
problem; but if, like you said, you haven't been able to compile any
kernels on your DX-50, you might try more conservative settings in your
BIOS (assuming they're not already as conservative as possible).
Again, this is just a suggestion of a possible cause, not necessarily the
answer to your problem.
