libstdc++: Add assertion to std::promise::set_exception (LWG 2276)
Without this assertion, the shared state is made ready, but contains
neither a value nor an exception. Add an assertion to prevent users from
accessing a value that was never initialized in the shared state.
libstdc++-v3/ChangeLog:
* include/std/future
(_State_baseV2::__setter(exception_ptr&, promise&)): Add
assertion for LWG 2276 precondition.
* testsuite/30_threads/promise/members/set_exception_neg.cc:
New test.
