This is because the expansion of the co_await into its control flow is not apparent to the machinery adding the target cleanup expressions. The solution being tested is simply to recreate target expressions as the co_awaits are lowered. Teaching the machinery to handle walking co_await expressions in different ways at different points (outside the coroutine transformation) seems overly complex. gcc/cp/ChangeLog: 2020-04-30 Iain Sandoe <i...@sandoe.co.uk> PR c++/94883 * coroutines.cc (register_awaits): Update target expressions for awaitable and suspend handle initializers. gcc/testsuite/ChangeLog: 2020-04-30 Iain Sandoe <i...@sandoe.co.uk> PR c++/94883 * g++.dg/coroutines/pr94883-folly-2.C: New test.
