File is attached. You don't need to be able to link (and won't be able to), but compiling it with `dmd main.d -c -g` causes an assertion failure:

    $ dmd main.d -c -g
    dmd: glue.c:958: virtual unsigned int Type::totym(): Assertion `0' failed.
    Aborted

However, using `-gc` works fine:

    $ dmd main.d -c -gc
    $

Source file that causes compiler to crash.

Main entry to my roguelike; the context is not important.

This cannot be compiled. It imports a whole bunch of files which are not
attached.
Please provide a complete test case.

Oops, sorry I didn't think that through.

Okay, rolling back to the commit that triggered the bug... and it's no longer triggered (and it was reliably when I submitted it). Nevermind, 'cannot reproduce' I guess. Bizarre.

If it's like the other ICE(glue.c) bug which is currently open, it might be compile-order dependent. Otherwise, please close as invalid.

Jimmied around a bit; no luck. If it comes up again I'll pay closer attention.

Created an attachment (id=463)
Entire project, run make; should fail with same assertion as before.

I figured it out; I had uncommited changes which I had reverted to post the project -- once I re-added them, the problem came back. In level.d:

alias TypeTuple!(int, int) Coordinate;

...


    Creature[Coordinate] mCreatureMap;   // <-- Remove this line and the
compiler doesn't crash.

I reduced that 1MB test case down to 3 lines <g>:

template Tuple(T...){
    alias T Tuple;
}

int[ Tuple!(int) ] foo;

---------
Segfaults on D1, as well; also happens on Windows as well as Linux. Curiously, this didn't segfault on 1.010 and earlier, but segfaults on 1.020. But I believe it was bad code generation on those early compilers, so not a regression.
