pacman seg fault ld-2.16.so in dmesg when ever calling pacman

Hello, i am am quite new in the forum so hopefully i found and investigated all areas to not post a new topic that is solved somewhere.

I am using arch on a 64 bit installation. I Installed yesterday skype by using "pacman -S skype". It worked quite well out of the box and after my work was finished i shut down my pc.
In the evening, i want to install some more software so i called "sudo pacman -S pidgin" and i get back "segmentation fault". A quick look and grep to dmesg i get a line like "pacman segfault at 8 ip $address sp $address error 4 in ld-2.16.so" for each cli pacman call i do. Since pacman itself is not running, i am a bit lost on how to solve this problem.

Can you please give me any kind of hint how i can solve this problem?

Thanks in advance,
nvb

[edit]
I forgot to mention that the installation is based on the "New install medium 2012.09.07".

[edit]
I also tried to use "ldd" but when i do:

ldd /usr/lib/ld-2.16.so

or

ldd /usr/lib32/ld-2.16.so

i get back

loader cannot load itself

.

If you need any additional information, please tell me so i can provide it. I am really a "little bit" lost :-(.

[edit]
I've done a:

ldd $(which pacman)

which leads into the following result

/usr/bin/ldd: line 117:   763 segmentation fault  LD_TRACE_LOADED_OBJECTS=1 LD_WARN= LD_BIND_NOW= LD_LIBRARY_VERSION=$verify_out LD_VERBOSE= "$@"

Re: pacman seg fault ld-2.16.so in dmesg when ever calling pacman

Since the worldwide web as the freenode irc channel couldn't help me (and i don't want to write this to blame someone), i reinstalled my system.

I also tried a chroot and "pacstrap /mnt pacman" with no effect. Also a "pacstrag /mnt base" couldn't  solve the problem since the installer wants to install systemd and my system still was systemvinit.

I'm crossing fingers that this will never happen again :-).
