            Bug ID: 96833
           Summary: Functors within target offload code
           Product: gcc
           Version: 9.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tobias.weinzierl at durham dot ac.uk
  Target Milestone: ---

I cannot declare a function

#pragma omp declare target
void foo( std::function<void()> x ) {=20
...

even though x is, whenever I use it, declared as offloadable, too. The
workaround is to make foo a template. It then works. Is this on purpose or a
bug?=
