# This test mimics the situation where an Ada program (including the
# runtime) is built with -flto.  In this situation, gcc emits the
# exception handling functions in the DWARF -- but in a CU that is
# marked as coming from "C".  This then triggered a bug causing the
# Ada catchpoint code not to find the underlying runtime functions.
