pacman -Su segfaults

melior · 2011-01-06 05:04:04

Hello, I'm new to the forums though I've been using Arch for almost a year now. Usually I'm pretty good about working through problems but this pacman segfault has me stumped. I can successfully install packages but I can't do the system update. Unfortunately I can't give you the exact date this started happening, but it was about a month ago, before which I would update pretty much every day.

Here is the output of pacman -Su --debug:

Per the wiki I downloaded the latest pacman source (3.4.1) and built it, but got pretty much the same result. I rebuilt again with debugging symbols, and ran it through ddd. My debugging skills are weak, but a simple backtrace provided the following:

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff644bd66 in strcmp () from /lib/libc.so.6
(gdb) bt
#0  0x00007ffff644bd66 in strcmp () from /lib/libc.so.6
#1  0x00007ffff7bd440f in check_arch (data=0x7fffffffe5e8) at trans.c:110
#2  alpm_trans_prepare (data=0x7fffffffe5e8) at trans.c:148
#3  0x000000000040ab5d in sync_trans (targets=<value optimized out>) at sync.c:641

#5  0x0000000000407817 in main (argc=<value optimized out>, argv=0x7fffffffeab8) at pacman.c:1240

So I put a breakpoint at trans.c:110 and stepped through...70 times (which is repeatable)...and the value that's there just before the segfault looks fine. The string in pkgarch is "x86_64" and arch is "x86_64".

Any ideas on what it could be or what to try next?

My setup:
AMD Turion RM-70
3 GB RAM
/: 71% free
~: 12% free
Plain Openbox desktop environment

Try pacman 3.4.2 and pacman from git

Allan · 2011-01-06 05:35:00

That bug is fixed in pacman-3.4.2. Do a "pacman -Syyu" and you should be fine.

Where in the wiki do you see that?

melior · 2011-01-06 06:41:28

Oh drat, my mistake. I guess that's what I get for waiting so long to ask for help. I'm up and running again, thanks!
