klibc sparc trouble with gcc 4.0

2007-11-05 Thread maximilian attems 
tried below fix, that is a partial revert of klibc
6fbd8fafdcc793135988733996d72b0298afe934
see git://git.kernel.org/pub/scm/libs/klibc/klibc.git
with belows fix klibc compiles fine on sparc with newer gcc,
but segfaults:


titan:~# strace -vfF /usr/lib/klibc/bin/fstype

thanks for looking at it.

use our own clzdi on sparc instead the one of libgcc

While i didn't see/used any big-endian machine/asm_dump, i just
speculate, since noone replied yet.

Re: unkillable dpkg-query processes

2007-11-05 Thread Bernd Zeimetz 

 So I'm not sure if the result is really useful for you - if not just let
 me know. I've attached the last ~10-20 sysrq-g outputs - as it was
 running in a loop I have a ton of them. In case you're wondering: http
 is aptitude's http method.
 
 The http module is stuck in a different place, I'll try to
 see if I can make sense of it.


Here's also some output from apt-get which got stuck in my unstable
chroot while I wanted to retrieve the klibc source to try to debug it...
