// When there is a weak hidden symbol in user code and a strong definition
// in the library, we test that the linker relies on the library version,
// as the default weak resolution semantics don't favour weak local definitions
// for XCOFF. This creates a conflict on std::bad_function_call, which is used
// by the std::function template instantiated in main.
