--- Comment #1 from Arsen Arsenović <arsen at gcc dot gnu.org> ---
both clang++ and g++ fail here, I believe it is the vector, string and
generator that you pass to vector_to_generator, test and test respectively that
expire before they get to be used in the coroutine body because. outlining the
values you use works:
int
main()
{
std::vector vec {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
std::string prompt { "test:" };
for (auto &i : test(vector_to_generator(vec), prompt))
{
}
}
... as does not using reference types in the helper functions:
coro::generator<const int> vector_to_generator(std::vector<int> test)
{
for (auto &i : test)
{
co_yield i;
}
}
coro::generator<const int> test(coro::generator<const int> source, std::string
prompt)
{
for (auto &i : source)
{
std::cout << prompt << i << std::endl;
co_yield i;
}
}
int
main()
{
for (auto &i : test(vector_to_generator({1, 2, 3, 4, 5, 6, 7, 8, 9, 10}),
"test:"))
{
}
}
there's a case to be made here about a missing diagnostic, however
