Trying to build DFeed using DMD git head results in an OPTLINK crash.

Steps to reproduce:

1) Build DMD/Druntime/Phobos from latest Git
2) Clone https://github.com/CyberShadow/DFeed and its submodules (ae)
3) rdmd --build-only -version=WindowsXP dfeed_web.d

I'm not going to even reduce this one unless there's an indication that someone is going to look at it (it literally takes days, and my previous OPTLINK report was ignored).

Why is this a regression? The linker hasn't changed.

It is a regression if you consider Optlink to be just an internal component of DMD "as a whole". Yes, it technically might not be a new bug, just a bug that didn't show up before. But the point is that code which compiled fine in previous versions would break if a new release was made right now.

The problem still exists in the DMD 2.060 release. The problem seems to be triggered by some code in a library. I can't build many of my projects with DMD 2.060 on Windows, which includes DFeed.

I'm facing the same problem with DMD 2.060 when taking address of constant from
module that was compiled into static library. It seems to be directly related
to number (or total size, probably) of constants in that module. Looks like
having too many constants causes bad code generation.
DMD 2.059 - no such problem.

Can someone please provide a zip with just the obj files and the linker command? I don't need the source code.

Created an attachment (id=1134)
A troublesome object file

Running either "dmd file.obj" or "link file.obj" triggers the error.
