Mount segfaluts in rc.sysinit

Question

Hi everyone,
since my last pacman -Syu last night I'm experiencing problems at boot time with the "Mounting Local Filesystems" phase.
I managed to find the problem:
/bin/mount -a -t $NETFS -O no_netdev
causes mount command to segfault.
Actually mount seems to his job correctly on common cases, the problem rises when I try to use the "-O no_netdev" option or the "-O _netdev" as found in /etc/rc.d/netfs.
here is strace output for "mount -a -O _no_netfs":

I tried to downgrade util-linux to 2.19-4 version an this solves the problem.
Is anyone having the same troubles?
