ldconfig segmentation faults

I've noticed ldconfig segfaults alot:

[light@betelgeuse ~]$ dmesg | grep segfault

Running 'ldconfig' in a terminal results in "Segmentation fault (core dumped)".

Running 'sudo ldconfig' does not result in segfault.

Here's strace for ldconfig:

[light@betelgeuse ~]$ strace ldconfig
execve("/usr/bin/ldconfig", ["ldconfig"], [/* 42 vars */]) = 0
uname({sys="Linux", node="betelgeuse", ...}) = 0
brk(0)                                  = 0x183d000
brk(0x183e1c0)                          = 0x183e1c0
arch_prctl(ARCH_SET_FS, 0x183d880)      = 0
readlink("/proc/self/exe", "/usr/bin/ldconfig", 4096) = 17
brk(0x185f1c0)                          = 0x185f1c0
brk(0x1860000)                          = 0x1860000
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x338} ---

Segmentation fault (core dumped)

Also:

[light@betelgeuse ~]$ pacman -Qo ldconfig
/usr/bin/ldconfig is owned by glibc 2.20-2

I've tried reinstalling glibc, deleting /var/cache/ldconfig/aux-cache as it was advised by this post and deleting /etc/ld.so.cache. Nothing seems to help.

How do I fix that?
