+ BFD assert handler
+
+ If BFD finds an internal inconsistency, the bfd assert
+ handler is called with information on the BFD version, BFD
+ source file and line. If this happens, most programs linked
+ against BFD are expected to want to exit with an error, or mark
+ the current BFD operation as failed, so it is recommended to
+ override the default handler, which just calls
+ _bfd_error_handler and continues.
