I'm using Windows 7 x64, but compiling 32-bit DMD. DMD compiles fine, but the linker warns about a "Warning 9: Unknown Option : LA". After that, when trying to compile Druntime, DMD chokes with this error:

"Assertion Failure: 'impl' on line 4930 in file 'mtype.c'".

I looked in the file, but all I could find on line 4930 was:

int TypeAArray::isZeroInit(Loc loc)
{
    return true;
}

So I'm not really sure what's going on here, though I obviously did something wrong compiling DMD.

Sounds like you're using an outdated OPTLINK. The /LA flag was added relatively recently and the newer DMD buildscripts use it.

Try updating your copy of DMC, maybe a newer one will have the up-to-date OPTLINK. Or just replace your DMC's OPTLINK with the one that comes with DMD 2.064.2:

Not sure what's up with that one, but I don't have any familiarity with mtype. Maybe it's just fallout from the earlier error?

Are you by chance trying to compile dirty druntime tree? (i.e. you've compiled it before?). If so, make clean first. I had an error along the lines of what you're describing after a recent pull, but I'm not 100% sure it's the same one.

Ah, yes, there's a rogue outdated OPTLINK hiding out somewhere in my path. That should fix it, I think.

It seems that while pointing to the correct link got rid of the linker warning, I still can't compile druntime.

It had been compiled before, so I went one further, deleting and re-cloning druntime. However, it still dies with the same assertion failure. Here's the relevant output before it dies:

What about dmd itself? Have you rebuilt it from scratch too?

Yes, DMD builds fine, and I tried to build druntime from a fresh DMD compile.

That is bizarre. Which git commits are you using for dmd and druntime?

Whatever's currently in master for both DMD and druntime.

win32.mak for druntime uses whatever dmd is in your PATH. My guess is on your machine it's not the same as dmd that's built in git working copy, i.e. it tries to use your installed dmd. I've just dusted off my Win7 VM, made pulls for dmd and druntime and built both, though I had to edit druntime's win32.mak so that DMD variable points to the dmd executable I've built.
