I compile it every day, and do not see those errors.
Sound like use off uninitialised var, as it's environment dependent.
There's at least 2 instances of that still outstanding in the
backend:

Thanks for pointing those out. Fixed now.
Thanks, but it didn't solve my problem.
I didn't think it would. Those issues were completely unrelated. Sorry
about that.
I'd like to emphasize that the problem is with my dmd.exe. If I use the
official dmd.exe, Phobos builds fine - so, it looks like I get a
slightly broken dmd.exe when I compile it from source.
Does anyone know which git commit is DMD 2.051? I think the best way
to find the problem is to compare the released binary with the one I
built.
Why not just get the latest dmd if you're interested in compiling from
source? Also, if you download dmd 2.051, you'll get the 2.051 source.
Oh, of course. Total mind lapse, I forgot the source is included with the
compiler.
Compiling the source from the .zip still yields a broken dmd.exe. My
version and the one from the .zip seem to differ in many small ways. The
first difference is that in main(), the .zip version calls a function to
get the address of errno, while my .exe accesses a variable directly.
Some disassembly for clarity:

Do we use a different version of the compiler or libc to compile DMD? I
believe I use the latest version at http://ftp.digitalmars.com/dmc.zip .
