Bug ID: 97433
Summary: C++20 Coroutines, Unexpected reordering of
await_resume, return_value and yield_value
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: davidledger at live dot com.au
Target Milestone: ---
Critical components of c++20 coroutines are being reordered. This means that
for Task types that return values using co_return and co_yield there is likely
incorrect results.
LLVM does not have this issue.
MSVC behaves the same as GCC.
I've outlined this problem in detail here:

The problem can be seen here, but the explaination is in the stack overflow
