--- Comment #1 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
The ICE triggers when the static variable is optimized out. This passes:

#pragma omp declare target
void foo ()
{
  static int __attribute__((used)) v;
}
#pragma omp end declare target

int main()
{
  #pragma omp target
  foo();
}

With s/used/unused/ it ICEs.
