Just as a test I tried it with ldc, and, as expected, there wasn't any problem.

So now I removed the repository version of dmd and dub, downloaded DMD64 D Compiler v2.072.0-b2, used dkpg to install it, and appear to get the same errors.

(Well, actually I removed the commenting out of the code, but it compiles and runs properly with ldc2.)

I don't think it's a problem of DMD. This is due to your gcc installation being hardened, that is, configured to produce PIE by default. To produce PIE, the linker needs to be fed PIC, which DMD does not produce by default. The -fPIC flags makes DMD produce PIC out of your sources. The problem is, libphobos2.a (the static version of Phobos) is not compiled with -fPIC, so even if your code is PIC, gcc will complain. The workaround is to use -defaultlib=libphobos2.so to dynamically link with the shared version of Phobos. Being it a shared object, it does not give any problem with PIE.

Looking on internet, I didn't find any clue about Debian shipping an hardened gcc, but this is the only cause I can think of for the behaviour you are experiencing.

Well, that certainly changed the error messages.  With

This seems to be problem with your installation, you probably have diferen version of dmd compiler and phobos library. So you should uninstall all your dmd packages and make sure there is no /usr/include/dmd left in your system. And instal dmd only from one source (d-apt idealy).

Hello,
From GCC 6.2, -fpie is becoming the default setting at compile and at link time.
As dmd uses GCC to link, now the code needs to be compiled with a special option.
Which means you need, at the moment, to add the following options to your dmd.conf:
 -defaultlib=libphobos2.so -fPIC
(the change from GCC is related to security and address space randomization).

I've done that 2 or 3 times.  If that's the problem, then there are different versions stored in the repository.  Since I'm on debian testing I'd been assuming that there'd been some system change since I'd last used the compiler, and the debs weren't yet up to date. The only updates to my system prior to the compiler breaking HAD been via apt-get.  Since then I've used dpkg remove and install a couple of times to try other versions of dmd with no benefit.
Currently dmd-bin version 2.071.2-0
              libphobos            2.071.2-0
              libphobos            2.071.2-0
so they're LISTED as being the same version.  And dmd.conf was installed by the deb, and is (eliminating the comments):
[Environment32]
DFLAGS=-I/usr/include/dmd/phobos -I/usr/include/dmd/druntime/import -L-L/usr/lib/i386-linux-gnu -L--export-dynamic

[Environment64]
DFLAGS=-I/usr/include/dmd/phobos -I/usr/include/dmd/druntime/import -L-L/usr/lib/x86_64-linux-gnu -L--export-dynamic

But somewhere during the process (which included the nightly system update) the error messages changed, and now:
dmd test.d
yields:
/usr/include/dmd/druntime/import/core/stdc/stdio.d(1121): Error: found 'nothrow' when expecting '{'

FWIW starting at /usr/include/dmd/druntime/import/core/stdc/stdio.d(1121)::
        asm nothrow @nogc
        {
            mov EDX, num;
            lock;
            inc _iSemLockCtrs[EDX * 2];
so nothrow isn't being seen as appropriate at the beginning of an asm block.  After that I think it gets confused as 1123 doesn't HAVE a brace (i.e. curly bracket) in it.

when you type dmd --version what it prints?

THAT WAS THE CLUE!
(that which follows is how I proceeded to the answer after that clue.)
 dmd -version
Error: unrecognized switch '-version'
and
dmd --version
Error: unrecognized switch '--version'
but
 dmd
DMD64 D Compiler v2.066.1

So thanks, that was the clue that I needed to fix the current problem.  (Once I have I'll probably be back where I started, but that's not certain.  That 2.066..stuff is one of my attempts to investigate what exactly was causing the problems, which must not have gotten completely uninstalled.

Yeah, now I'm back to:
...
/usr/bin/ld: /usr/lib/x86_64-linux-gnu/libphobos2.a(aaA_4f5_2d5.o): relocation R_X86_64_32 against symbol `__dmd_personality_v0' can not be used when making a shared object; recompile with -fPIC
...

and
dmd -defaultlib=libphobos2.so test.d
yeielding
/usr/bin/ld: test.o: relocation R_X86_64_32 against symbol `__dmd_personality_v0' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: error: ld returned 1 exit status
--- errorlevel 1

but
dmd -defaultlib=libphobos2.so -fPIC test.d
works.  It shouldn't be required (as in the default /etc/dmd.conf should handle it correctly, but I can deal with it now.
