--- Comment #12 from Richard Biener <rguenth at gcc dot gnu.org> ---
How do I reproduce this?  I tried, on x86_64-linux an all-language bootstrap
using gdc-13 for the first stage and that succeeded.  I'm now trying again
with gdc-12, just --enable-languages=d and an explicit
--with-built-config=bootstrap-debug
