commit 06a9f9e6ace98b3c7cd479a88c5bbb310090307e
Author: Wesley Bland <wbland at anl.gov>

    Fix null pointer deref in pending check
    Depending on how some uninitialized data was prepopulated, the ibsend
    check was periodically crashing out in the call to
    MPID_Request_is_pending_failure. Some simple sanity checking to make
    sure the input data wasn't NULL takes care of this.
