Compiler segfaults if not compiling with -debug #dbugfix

I'd like to bring #dbugfix attention to issue 18026: Stack
overflow in ddmd/dtemplate.d:6241,
Put simply, I can only compile my code with -debug. Without it,
dmd and ldc segfault on all of Linux, Windows and OSX.
The smallest I can dustmite it to is to 66 lines (according to
dscanner) across a few modules. ag0aep6g managed to reduce it
further into one file at
https://issues.dlang.org/show_bug.cgi?id=18026#c10, which he
notes mostly segfaults but sometimes manages to compile. I can't
reproduce his snippet on my machines, it may or may not work for
you. The fickleness is a theme.
There's no place to point and say "ah, there's the bug". It's
just something emergent from a hundred little things that
together make up something that segfaults compilers. I only know
that it started when I added a big named enum with a few hundred
members, and after that it's been popping up regularly. Sometimes
it just goes away after I make some innocent, unrelated change.

You can try the full thing either with dub (plain or release), or
> $ dub build -b plain
> /usr/bin/dmd failed with exit code -11.
> $ dmd -c source/kameloso/*.d source/kameloso/plugins/*.d
> Segmentation fault (core dumped)
> $ ldc source/kameloso/*.d source/kameloso/plugins/*.d
> Segmentation fault
Help. Please. :c
