Bug ID: 99827
Summary: [coroutines] co_await on function receiving
initializer list of shared pointers causes ICE
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: inf17092 at lehre dot dhbw-stuttgart.de
Target Milestone: ---
When using coroutines and awaiting the return value of a function receiving an
initializer list of shared pointers, the tree check fails with the following
error:
internal compiler error: tree check: expected record_type or union_type or
qual_union_type, have array_type in build_special_member_call, at
cp/call.c:10143
When using the promise type `promise::promise_type`, the following function
produces the error. In this case, `func1` receives the initializer list of
shared pointers and returns an awaitable.
promise task() {
co_await func1({ std::make_shared<int>(1) });
}
You can find a short sample file demonstrating the bug and the full error
output here: https://godbolt.org/z/489EcWdb3. The bug also occurs with version
10.2.0-5 on my local Ubuntu system but not with version 10.2.0 on godbolt.org.
