I'm building my fourth LFS system and started on xorg 7.2 yesterday.
Once I untangled some dependency issues (which I really should have
documented to save others the hassle), everything went smoothly until
the server itself.  It gets as far as
xf86ScanPci and then hangs - BOY does it hang.  All other processes came
to a complete halt and I thougth the whole system was locked up; then it
returned to the bash prompt saying gcc: Internal error: Killed (cc1).

Build system is an AMD Sempron 2100+ with 512MB RAM.  OS environment is
a fresh LFS build, with kernel 2.6.21.5 and gcc 4.2.0.

The first time, I was chrooted into the new system so I could keep my
old system running to check email and do the occasional work-related
task to keep the boss happy, and I thought the compile requirements of
xf86ScanPci might be so great that 512MB wasn't enough to compile that
while running X, fluxbox, Evolution, Gaim, and Firefox all at once - the
crash brought all of those down, too.  So I tried again without anything
else running, and got the same results.

I thought maybe trying to build it in the chroot environment wasn't
working, so I rebooted into the new system exclusively and tried again
with the same results.  I specifically told it to run only one job at a
time (although I think that is the default) and it still didn't help.  I
went into the hw/xfree86/scanpci/ directory and tried to make just that
one item.  Same results, although I got an interesting message about
memory failure that would not pipe to a log file; it only displayed to
the screen.

Finally I keyed in the specific gcc line that compiles xf86ScanPci.c by
hand, and it compiled with no errors.  Then make built the rest of the
system without any further problems.

So I got past it and X seems to work OK, even running DRM tests fine,
but I worry that I'm ignoring whatever underlying problem caused the
memory crash in the first place.

Has anyone else encountered this problem?  Or does anyone have a
suggestion on what I can test for?
