I have a large named enum (currently 645 members) of IRC event
types. It's big by neccessity[1].
I'm using dub, and both dmd and ldc successfully build it in test
and debug modes, but choke and die on plain and release. I
bisected it down to when I did a big addition to the enum to
encompass virtually all event types there are.
dmd -v:
[...]

function kameloso.common.KamelosoLogger.finishLogMsg
zsh: segmentation fault (core dumped) dmd -c -v -w -d
-version=Have_kameloso -Isource/ source/arsd/dom.d
Where it stops here varies if I comment stuff out, so I don't
think the Logger is at fault.

What can I do? Merely copying the enum into a test file and
compiling with an empty main does nothing, it doesn't seem to be
enough to replicate the bug.
(Arch/Manjaro 64-bit, dmd 2.077.0, ldc 1.5.0 based on 2.075.1)
