--- Comment #6 from Tobias Burnus <burnus at gcc dot gnu.org> ---
[x86_64 build/host with target nvptx]

.../gcc/cc1 -fpreprocessed task.i -quiet -dumpbase task.c -dumpbase-ext .c

Another variant of reducted testcase:

struct gomp_task { void *fn_data; };
gomp_target_task_fn (void *data) { __builtin_unreachable (); }
gomp_create_target_task ()
{
  struct gomp_task *task;
  task =3D gomp_malloc (sizeof (*task));
  gomp_target_task_fn (task->fn_data);
