Commit 31f97
(shttps://github.com/D-Programming-Language/dmd/commit/31f974a03de4372a7f95801b3e4f5a09f052ee1e)
introduced a bug that causes DMD to crash with a segmentation fault upon
invocation.

It looks like importing certain modules, like std.stdio, causes the crash.  (A
simple "Hello world" program cannot be compiled.)  The modules do not have to
be actually used; only imported.  Importing an empty module does not trigger
the crash.

Tested under a completely new installation of Arch Linux.  32-bit everything. 
I built a Git checkout of DMD, but pointed it to the imports and binaries from
the 2.059 .zip file from dlang.org.  (I was in the process of upgrading the
entire toolchain, and Phobos and DRuntime cannot be compiled with an older
DMD.)
