on old Red Hat : 9.4.0 fails in stage3 bootstrap due to __asm__ ("ntp_gettimex") __THROW;

[Dennis Clarke]

*baffled* again here.

At this point I am truely confused what the issue can be when a
bootstrap fails in stage 3?  Not in stage 1 and not in stage 2 but
the whole process throws a fit in stage 3 ?

Sort of has me thinking something strange is truely afoot here.

May as well get this dragged out into the open. This is an old Red Hat
Enterprise Linux 6 machine and there is just no way at all to install
anything from any repo ever again. Anything needed has to be built from
sources. Not a problem given very little is actually needed.  A more up
to date compiler would be nice.

The source tree was extracted along with the sources to gmp/mpfr/mpc and
the isl lib into the tree in the prescribed and described manner. No
tricks or anything there.

I doubt that makeinfo is a concern but who knows.

In any case the compile runs neatly all night long and then dies in
stage3 thus:

There the process blows up in stage 3.

mimas$ cat stage_current
stage3
mimas$

Maybe there are some CFLAGS that can get around this somewhere?

Any thoughts at all from anywhere would be great.

Risking the self reply but maybe this is related :

     Bug 61955 - libsanitizer fails to compile on RHEL4
     https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61955

The kernel on this box is old. This old server was installed from the
actual red coloured cardboard box and the installation DVD. I even
have the cute bumper stickers in the box still. Thus the Linux kernel
here is from way way back :

mimas$ cat /proc/version
Linux version 2.6.32-71.el6.x86_64 
(mockbuild@x86-007.build.bos.redhat.com) (gcc version 4.4.4 20100726 
(Red Hat 4.4.4-13) (GCC) ) #1 SMP Wed Sep 1 01:33:01 EDT 2010
mimas$

Looking into https://cdn.kernel.org/pub/linux/kernel/v2.6/  my guess is
somewhere from 2009 or so.

The last comment from Andrew Pinski in that bug report suggests it may
be possible ( no promise ) to start over with --disable-libsanitiser and
hope for the best.

If you spell it with a 'z' then yes.

Oh, right. It is --disable-libsanitizer and the bootstrap is running.
