DMD 2.063 produces broken binaries

[Jerry]

Hi folks,

I've downloaded the current dmd 2.063 zip and tried it out.  This is
Ubuntu 12.10 x86_64.  Every program I compile segfaults when I try to
run it.  As a simple example:

jlquinn@wyvern:~/re/test$ cat junk.d 
import std.stdio;
void main() {
  writeln("Hi");
}
jlquinn@wyvern:~/re/test$ /home/jlquinn/dmd2/linux/bin64/dmd junk.d
jlquinn@wyvern:~/re/test$ ./junk
Segmentation fault (core dumped)

The gdb backtrace is somewhere in __libc_start_main, before main() is
run.

I assume I'm not in the majority, but I literally can't compile and run
anything.

Any help would be appreciated
Thanks
Jerry
