+"""
+Tests that we can call functions that have definitions in multiple
+CUs in the debug-info (which is the case for functions defined in headers).
+The linker will most likely de-duplicate the functiond definitions when linking
+the final executable. On Darwin, this will create a debug-map that LLDB will use
+to fix up object file addresses to addresses in the linked executable. However,
+if we parsed the DIE from the object file whose functiond definition got stripped
+by the linker, LLDB needs to ensure it can still resolve the function symbol it
+got for it.
