Thread 1 (Thread 0x7f0a2d3378a0 (LWP 1278)):
#0  WriteToClient (who=0x7f0a2f59d8e0, count=32, __buf=0x7fff8a94c8e0) at 
../../os/io.c:789
        oc = 0x7f0a2f3453c0
        oco = 0xffffffff00000001
        padBytes = <optimized out>
        buf = 0x7fff8a94c8e0 "s\311!I~\020R\001\003\004"

The oco pointer address looks wrong.  This seems to be something wrong
in the server, likely not the driver.

WriteToClient (ClientPtr who, int count, const void *__buf)
    ...
    oc = who->osPrivate;
    oco = oc->output;
    ...
    if ((oco = FreeOutputs))
        {
            FreeOutputs = oco->next;  // line io.c:789
        }
