commit ff5227bf023da4e9c07af99d77ddcfc02bb995a8
Author: Mandeep Shetty <[email protected]>
Date:   Thu Sep 24 13:42:39 2015 -0700

    Fix segfault when calling OCCancel ()
    
    This fixes the client side crash in IOT-733.
    OCCancel () allocates a pointer that is free'd in routingutility.c.
    Although the pointer was passed in as reference into routingutility and
    is re-assigned with a new malloc'ed pointer, OCCancel() free's the old
    pointer.
    This is because there two structs that are being passed around. The
    pointer that is double free'd is free'd twice as part of two DIFFERENT
    structs. Got rid of the extra struct to keep things consistent and
    resolve the crash.
    
    If accepted, this changeset should be cherrypicked to 1.0.0-dev.
