(did you try 9.3?) It seems so, yes. Yet gdc 9.1.0 was good enough until now, and if there's an issue, the requirement should at least be documented. I'm currently running a bootstrap with gdc 11.1.0 instead, which is well into make check. Will try gdc 9.4.0 (which is currently building, switching from gas 2.32 to 2.38 if that matters) afterwards.
