Description Chris Ricker 2003-08-18 19:11:06 UTC
I yum'ed a fresh severn install to today's rawhide. Now, kudzu segfaults:

# /etc/init.d/kudzu start

Comment 7 Chris Ricker 2003-08-18 19:20:50 UTC
Only eth0, eth1, and lo config files. eth1 is disabled in the bios (onboard VIA
rhine), but w/o ifcfg-eth1 present, it still segfaults

Only thing unusual is that NOZEROCONF is in all the configs, and lo is a file
rather than a symlink (symlink stuff is a PITA whenever you upgrade if you've

Comment 8 Chris Ricker 2003-08-18 19:40:04 UTC
Hmm, not related to ifcfg-eth1. I re-enabled that in the bios, and it still

Comment 12 Bill Nottingham 2003-08-18 19:50:07 UTC
hardware is probably irrelevant.

Can you run MALLOC_CHECK_=2 strace kudzu ..? Is the strace appreciably
different? (It's running OK here with those files.)

Comment 13 Bill Nottingham 2003-08-18 19:50:55 UTC
Alternatively, a gdb backtrace would be nice; I'll chuck the debuginfo package
on people.redhat.com/notting/kudzu/

Comment 14 Chris Ricker 2003-08-18 20:24:55 UTC
Hmm, I did the MALLOC_CHECK_ strace (what's that doing exactly? what its name
suggests?). That's a 31 meg strace though, so I'll have to post it on a web
server somewhere ;-)

I haven't so far managed to get gdb to backtrace. It's not dumping core, and if
I just run gdb kudzu, and then try to run it, I get the error:

Starting program: /usr/sbin/kudzu
30: No such file or directory.

Program exited with code 01.

Comment 15 Chris Ricker 2003-08-18 20:26:24 UTC
Hmm, FWIW, redhat-config-packages segfaults as well, and it looks like the same
cause. Its strace goes:

4444  open("/etc/sysconfig/network-scripts/ifcfg-eth0", O_RDONLY) = 4
4444  fstat64(4, {st_mode=S_IFREG|0644, st_size=53, ...}) = 0
4444  read(4, "DEVICE=eth0\nBOOTPROTO=dhcp\nONBOO"..., 53) = 53
4444  close(4)                          = 0
4444  open("/etc/sysconfig/network-scripts/ifcfg-eth1", O_RDONLY) = 4
4444  fstat64(4, {st_mode=S_IFREG|0644, st_size=52, ...}) = 0
4444  read(4, "DEVICE=eth1\nBOOTPROTO=dhcp\nONBOO"..., 52) = 52
4444  close(4)                          = 0
4444  open("/etc/sysconfig/network-scripts/ifcfg-lo", O_RDONLY) = 4
4444  fstat64(4, {st_mode=S_IFREG|0644, st_size=269, ...}) = 0
4444  read(4, "DEVICE=lo\nIPADDR=\nNETMA"..., 269) = 269
4444  close(4)                          = 0
4444  --- SIGSEGV (Segmentation fault) @ 0 (0) ---

Comment 16 Bill Nottingham 2003-08-18 20:28:22 UTC
gdb kudzu
set args -t 30

You can't pass args to the program on the gdb commandline.

Yes, it's the same segfault. I've made a tweak in CVS so it will (hopefully)
stop crashing things like r-c-p and r-c-xfree86, but I still need to track down
the bug.

Comment 17 Chris Ricker 2003-08-18 20:35:54 UTC
Ah, thanks. Now I've got a backtrace:

Program received signal SIGSEGV, Segmentation fault.

On the screen, it was asking if I wanted to configure my newly detected video

strace with malloc check

If it will be useful, I've also attached the strace done with MALLOC_CHECK_=2.
This is only 28k bzip2'ed, so it should be small enough for bugzilla. If not,
and you need it, let me know and I'll put it on a web server somewhere.
