Bug 22494

Was it alphaev6.rpm which you updated to or was it alpha.rpm?
I could not reproduce it with alpha.rpm on 4way AlphaServer ES40 in a chroot,
neither could I reproduce it with alphaev6 glibc unpacked to some directory
and running ./ld-linux.so.2 --library-path ./ `which uptime`
I hope somebody with physical access to some alpha will try to reproduce this
soon.

It was glibc-2.2-9.alphaev6.rpm. The funny thing is that those commands
do not always crash. They do in 70% of cases and it depends on system load.
They crash more often if run by root than by some other user. Also system
daemons like sshd or mysqld start to behave very odd.

Are you able to see the crashes when you boot that box into UP kernel?
It might as well be a kernel bug (especially if it is not reproduceable
100% of the time). I think Richard Henderson spoke recently about some ASN
handling bug in kernel.

The ASN patches are in 2.4.0-test13-pre3, could you by chance try that
kernel to see if the random crashes go away?

Well, I will try to do that over the weekend, probably with 2.2.18 and
patches... It is a production machine...

Hi there

Just updated my ES40 test system this morning with glibc-2.2-9.alphaev6.rpm and
I have the same problems as Andrej.

Here is the bootup log with SMP:

I can access the system over the console, not over the network though. I did not

I`ll see if I can check it with kernel 2.4.0.

Actually, it might as well be a bug in some alphaev6 optimized routines
which appeared in glibc recently, I'll build now glibc-2.2-9.1 with all the
alphaev6 specific assembly disabled and will make it available to you then.
I had only 2-3 tests failing during alphaev6 make check and those did not fail
when I ran them for the second time, so I thought it is because of the ASN
issues. But as the above log makes it clear it crashes on UP as well, it might
as well be some weird bug in ev6 assembly, we'll see.

If you want, glibc-2.2-9.1 (ie. ev6 without new ev6 optimized assembly) can be
had at ftp://ultra.linux.cz/private/alphaev6/ (as soon as scp finishes).
I've done no testing on it so far though.

I have tried glibc-2.2-9.1.alphaev6.rpm from ultra.linux.cz. I have installed
this and the "offical" update into separate temporary dirs and tried
./ld-linux.so.2 --library-path ./ /usr/bin/uptime
on both. The 2.2-9 dumps core as before, while 2.2-9.1 works OK!!!
So it seems to be alphaev6[7] issue of glibc.
Thanks for help.

I`m running glibc-2.2-9.1.alphaev6.rpm from ultra.linux.cz now and it looks
good, no Segmentation Faults so far.

I found the bug in alpha/alphaev6/memcpy.S plus one bug in realloc which
was triggered by the new memcpy, it will be fixed as soon as new glibc-2.2-10 is
built.

Should be fixed in glibc-2.2-12.
