Yes. At the moment init_unit_test_suite invocation is not guarded. I should 
probably change this. At the moment you've got 2 options:

1. Use global fixture (1.34.0) instead of init_unit_test_suite
2. use framework::setup_error to report initialization error

Because C++ doesn't provide a way ;). Do you know one?
