gcc3.3.2, kernel-2.6.6, and Mandrake 10.0 compiling problem.

[Eric Gillespie]

Got a small problem, folks.  I've got a Mandrake 10.0 system (upgraded in 
bits and bobs, but that's not really relevant), with gcc-3.3.2, binutils-2.14.90.0.7
and a plain (linux.org) kernel tree patched from 2.6.0 to 2.6.6. No -mm, no
-ac, nothing except base.

The system's a K6-2 @533 MHz, 192Mb memory (and 308 Mb swap). Plenty of hard
disk space available.

I was trying to compile the tree (make V=1) and got the following output.

Fine, I said. I eliminated all the obvious aspects, such as CPU overheating,
bad memory, etc. This particular item happened consistently, and happened no
matter what the load on the machine, nor what time of the day. Other programs
seem to compile fine on it (i.e. ne2k-pci-diag.c, once I turned all the
multi-line strings into one single string with embedded newlines).

I tried running each section, from preprocessing (.c -> .i,  .i -> .S) and
found it failed in the cc1 section of compilation. The output of gcc --verbose
+plus_all_other_args runs like this:

As you can see, it doesn't really give me any other info that I didn't have.
Now, where should I go from here?  I'm not really willing to try gcc-3.3.3 or
3.4.0, due to not having them available without upgrading to cooker...yeeesh.
However, given the simplicity of the function, I don't think this should
be happening. I really DON'T think it's an "internal compiler error" -
still, I have been known to be wrong before.

I looked through the newsgroups for other likely affected people, but nobody
particularly seems to spring to mind.

I will try with the 2.96 compiler too, but I don't expect to get too far
with that, as people have been having trouble compiling 2.6.x kernels
using the 2.9x compilers.
