--- Comment #7 from Eric Gallager <egallager at gcc dot gnu.org> --- the pb_ds directory might be removed in the future; might want to retitle this to clarify that the underlying issue is actually in the compiler and the pb_ds testcase only happens to expose it, so that this bug doesn't get closed when the removal happens... (assuming my read of the issue is right)
