Speculative request for insight

Hi,

My first attempt to use D-YAML has resulted in this error:


ldc2 -I=. -Jsource/resources -J. -I/usr/include/d/gtkd-3/ -I/home/users/russel/Built/include/d -I/home/users/russel/Built/include/d/yaml -I/home/users/russel/Built/include/d -g -of=me-tv -L-L/usr/lib/x86_64-linux-gnu/ -L-lgtkd-3 -L-ldl -L-L/home/users/russel/Built/lib -L-ldinotify -L-L/home/users/russel/Built/lib -L-ldyaml source/about.d source/channel_names.d source/configuration.d source/control_window.d source/frontend_manager.d source/frontend_window.d source/inotify_daemon.d source/main.d source/preference_dialog.d source/preferences.d

I reported it on the D-YAML issues on GitHub: 

https://github.com/dlang-community/D-YAML/issues/136

but the apparent claim is that it isn't a D-YAML issue per se, that this same
problem arises in other contexts.

It is the case that the Dub build of the same code completes fine, so there is
a hint that it might be an LDC specific issue.

So I am grasping at straws a bit I know, but does anyone here have any
thoughts as to what might be wrong?

I am using Debian Sid, with packaged LDC:
