For host execution, we print something like:
terminate called after throwing an instance of 'std::bad_cast'
what(): std::bad_cast
Aborted (core dumped)
{ dg-output {.*std::bad_cast} { target openacc_host_selected } }
For GCN, nvptx offload execution, we don't print anything, but just 'abort'.
TODO For GCN, nvptx offload execution, this currently doesn't 'abort' due to
the 'std::bad_cast' exception, but rather due to SIGSEGV in 'dynamic_cast';
