What can I check ?

In fact I never could complete a compilation from the CVS, although I 
tried many times during last months.

What it sounds like is that stage1 is being miscompiled by the compiler you are using.

Can you try to bootstrap with a different compiler first.

Thanks. OK, my gcc 3.3 was probably broken. So I updated :
gcc, binutils, glibc-devel

But now I have an unstable Mandrake cooker version :-((

gcc --version
gcc (GCC) 3.4.1 (Mandrakelinux (Alpha 3.4.1-3mdk)

I should probably download a stable binary.

Now I get to stage 2 !

I might go out on a limb and say that you have some hardware problems.

Are you joking at me ?
I used the laptop for 2 or 3 months, it's true that I had some freezes, 
but I thought it was due to instable Mandrake 10.
Seriouly, how can I check my hardware ?

This week-end , I'll test thez bootstrap with Fedora Core 2 and let you 
know.

The key thing to check is whether the bugs are reproducible.  If you 
type "make bootstrap" 3 times in a row, do you get the exact same 
failure every time?  You don't have to do builds from scratch.  You can 
just try to continue builds from where they failed.

If you get the same failure every time, then this is likely a gcc bug. 
If you get a different failure every time, then it is likely that this 
is either a kernel bug, or a hardware problem.

If you are having sporadic kernel/hardware failures, then you may be 
able to complete a build if you just keep typing "make bootstrap" enough 
times.

This probably isn't the right group to ask about detecting hardware 
problems.  Maybe there is a linux FAQ about this somewhere?  I don't 
know if there are free programs for this.  There are probably commercial 
Windows based products for PCs.  The BIOS might have some memory testing 
stuff.  Trying a stable linux kernel is probably an easier and cheaper 
and safer solution than messing with hardware, so I'd suggest doing that 
first.
