Small update.

I no longer experience this with the dmd and ldc from the Arch/Manjaro
repository, even when checking out the old `overflow` branch used in the
original report.

I do experience it when I build dmd myself (with Digger). It is not possible
for me to build and use my own dmd.

Has there been any changes since last? Having a compiler that does work is
comforting, but also discomforting to know it may break when it feels like it.
