--- 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)
