(Similarly to bug 3585 ...)
There are cases when the client's reliable command buffer is overfilled. The
client handles the situation by disconnecting from the server. Which means
sending another reliable command ("disconnect"), which results in another error
call, etc.

Technically speaking:
CL_AddReliableCommand()
 Com_Error() // overflow, anything could be behind this
  CL_Disconnect() // send "disconnect"
   CL_AddReliableCommand() // already overflown
    Com_Error()
     Sys_Error()
      CL_Shutdown()
       CL_Disconnect()
        CL_AddReliableCommand() // ah, not again!
         Com_Error()
          Sys_Error()
           CL_Shutdown() // recursive shutdown, return
           Sys_Exit()
