How reproducible:
Always

Steps to Reproduce:
1. make menuconfig
2. make dep
3. make bzImage

=> it fails on sg driver...
	

Actual Results:  gcc -D__KERNEL__

Expected Results:  ...compiling...

Additional info:
Comment 1 Jakub Jelinek 2001-07-12 09:56:59 UTC 
Is it always reproducible on the same file/function?
If not, it is probably hardware problem, if yes, then please mail me exact
preprocessor output (add -save-temps to the above and attach here sg.i;
though AFAIK we are compiling 2.4.6's sg just fine here with that compiler).
Comment 2 Laurent CREPET 2001-07-12 12:36:37 UTC 
Yes, it seems to be reproductible. I tried 3 or 4 to compile, than every try has
failed on sg.o !
That what I set:
> How reproducible:

when I submit the problem.

What kind of hardware problem do you think off ? Bad memory chip ?
I think I'll download and run memtest86 to check.
Comment 3 Laurent CREPET 2001-07-12 13:47:46 UTC 
Done again from:
  - my old kernel tree
  - a new one, extracted from linux-2.4.6.tar.bz2 from www.kernel.org
  - a new one, made with 2.4.0 sources, plus all 2.4.1 to 2.4.6 patches
     (using scripts/patch_kernel <kernel tree path> <patches path>

All compile ! Don't understand.
I'll run memtest86 to check if it is something with bad memory chip.
The main problem is that I don't remember what was running when I tried to
compile the kernel, and the compilation failed... Don't remember if the system
was heavy loaded or not...
