--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Reduced testcase:

#pragma omp declare target
struct Surface { virtual double sag(); };
#pragma omp end declare target
Surface main_devPtr;
main() {
#pragma omp target
  main_devPtr.sag();
}


Printing in 'output_constant' (varasm.cc:5302) the value of 'exp' shows:

 <ssa_name 0x7ffff6e0df78
    type <pointer_type 0x7ffff6ffc9d8
