strace cant parse struct msghdr RHEL

[Al Gambardella]

I downloaded strace version 4.13 and was able to build the source code
and produce the strace executable. I need to see the all of the
payload in the recvmsg and sendmsg calls. including the iov style
arrays

My system is RHEL Server 5.8 Tikanga. Kernel version 2.6.18-348.el5

When I run strace with the following command line:
./strace -p <mypid> -e 'trace=recvmsg,sendmsg' -e write=8 -e read=8

I am getting the following output (which contains errors). Can someone
explain why and if this can be fixed?

sendmsg(8, {msg_name=NULL, msg_namelen=-7630976, msg_iov=NULL,
msg_iovlen=92, msg_control=[{cmsg_len=2048, cmsg_level=SOL_IP,
