commit d6b183074686940e8533b6fa377b098ec87a7f12
Author: Mark Wielaard <mjw@redhat.com>
Date:   Wed Jan 6 16:24:56 2010 +0100

    Fix get_cfa_ops failure on shared libraries.
    
    The fix for PR10923 (fafeaf) wasn't completely correct. All cfa lookups
    need to be done through the relative pc (without bias) of the module we
    are looking in.
    
    * dwflpp.cxx (translate_location): Call get_cfa_ops with relative pc.
