            Bug ID: 101567
           Summary: Gcc incorrectly allows co_await operator inside
                    catch-block
           Product: gcc
           Version: 11.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fchelnokov at gmail dot com
  Target Milestone: ---

According to the standard "An await-expression shall appear only in a
potentially-evaluated expression within the compound-statement of a
function-body outside of a handler."

But GCC currently allows co_await operator inside catch-block, which lead to
very weird results:
