Hi all,
these changes will allow backtrace even through objects without 
debug_frame section. Note that gcc must produce all information 
necessary in eh_frame (perhaps -fasynchronous-unwind-tables flag?).

         * dwarf2cfi.c (frame_state_for): Added safety check for a valid
         fde->cie_ptr.
         (dwarf2_build_frame_info): Added handling for eh_frame.

OK to commit to mainline and branch?
