Comment 1 Karel Zak 2006-06-26 10:50:10 UTC
It works for me. There must be wrong anything other in your system, because your
report is alone, although x86_64 is used very often...

$ rpm -qa --queryformat "%{name}-%{version}-%{release}.%{arch}\n" | grep procps

$ ps -ef | wc -l

Comment 3 Albert Cahalan 2006-12-25 20:20:56 UTC
For troubleshooting, he might try installing the upstream version.
It's very easy to do:

wget http://procps.sf.net/procps-3.2.7.tar.gz
tar zxf procps-3.2.7.tar.gz
cd procps-3.2.7.tar.gz
make install

Comment 4 Tomas Smetana 2007-05-14 13:50:37 UTC
I can't reproduce the problem and nobody else reports this. Since the submitter
did not provide any further information I'm closing the bug.

Comment 5 Marc Schlensog 2009-07-09 10:27:50 UTC
Sorry for re-opening this ancient bug but it still seems to be present in F11.
It seems to be a bug related to the hardware, as I seem to have the same system (AMD Solo). I don't know if anyone is still interested in fixing bugs that only show up on 7yr old pre-production hardware. But if so, I'll try to be helpful in any way possible.

Here some more information:

Comment 6 Tomas Smetana 2009-07-09 11:27:29 UTC
Hello Marc,
  you can try to install the debuginfo packages ("debuginfo-install procps") and try to run ps with valgrind or gdb to get some more clues.

Note: I have changed the assignee to the recent maintainer.  I think this bug is worth investigating since it might show some more generic problem.  I'd like to help here if possible but the actual decision on reopening the bug is up to Dan.

Comment 7 Marc Schlensog 2009-07-09 11:59:31 UTC
Hi Dan,

that's already more than I expected :)

Here is the output for top (message is identical for the other programs that segfault):

Starting program: /usr/bin/top 

Program received signal SIGSEGV, Segmentation fault.
0x000000349e60ab2d in set_fast_math () at ../../../gcc/config/i386/crtfastmath.c:97

Comment 8 Daniel Novotny 2009-07-09 13:04:57 UTC
hello Marc,
I tried to google "crtfastmath" and "set_fast_math" a bit and found this:


so I made a build of procps without the -ffastmath compile switch:
you can try it here:


and see if it helps...

Comment 9 Marc Schlensog 2009-07-09 14:05:42 UTC
Hi Dan,

yes, that actually fixed it. Very cool :) That's more than I was expecting when I re-opened the bug.

Thanks and best regards,
