I don't think this is CVE-2014-3917.  It looks like you're hitting this BUG:

BUG_ON(context->in_syscall || context->name_count);

Can you send the output of:

auditctl -l [run as root]


dmesg |grep audit

Are you using ptrace or anything like that (e.g. strace) when you
trigger this?  Are you using a funny glibc version?  Do you have
selinux or something like that enabled?
