Seems to only occur for 64-bit binaries built with DMD. 32-bit ones work 
fine. Also, it seems to work for people who haven't enabled the 
precise-proposed repository.

(And of course, it worked just fine either way in 11.10.)

Digging further, it appears that in src/gc/gc.d:gc_init() in druntime, 
the ClassInfo object resulting from GC.classinfo contains bogus data (or 
something). It seems to fetch the right object, but ci.init.length is 0 
and ci.init.ptr is null.

Anyone have any ideas?

That won't help you much, but on Kubuntu 12.04 (32bits), the 2.060.deb
is recognized but stops after a time (or, at least, stays dozens of
minutes without doing anything visibly, which seems wrong to me).
Installing 2.060 by hand have it work perfectly.

Yeah, the entire 32-bit tool chain works fine for me as well (or the 
64-bit one but building 32-bit binaries). It seems to only crash and 
burn when outputting 64-bit binaries one way or the other.

I have dmd64 on ubuntu 12.04 64 bit, and it works fine.

The code:

import std.stdio;

void main()
{
	writeln("Hello, world!");
}

Compiled with dmd test.d -m64
works fine, it prints "Hello, world!".

Did you forget to uninstall dmd 2.059?

No, this is a clean system with no trace of any D compiler before 2.060.

I would say rebuild druntime with debugging symbols so you can get the
line where it crashes... but I guess building the library yourself
will resolve the issue (as things have a habit of usually doing).

I've built an special 64-bit dmd v2.060 deb package. It includes dmd, druntime

Other binaries and 32-bit phobos library was removed.
