I'm not sure why did strace segfault in this situation. And I can also
reproduce this segfault in
strace -- version 4.5.19(CentOS 6.4 64bit).

But I tried it in another system of strace -- version 4.8(Ubuntu 14.04
64bit), There aren't any segfaults and everything
goes right, I can get the expected output in this situation.

Maybe you can just upgrade your strace to the latest stable version
and hava a try again.
Hope this help.

Thank You
