Good thought.  I still seem to be able to build 32 bit C apps though:

chad at Hugin ~/cprojects/ctesting $ gcc trivial.c -o trivial
chad at Hugin ~/cprojects/ctesting $ file trivial
trivial: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically
linked (uses shared libs), for GNU/Linux 2.6.9, not stripped
chad at Hugin ~/cprojects/ctesting $ ./trivial
chad at Hugin ~/cprojects/ctesting $ gcc trivial.c -m32 -o trivial
chad at Hugin ~/cprojects/ctesting $ file trivial
trivial: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped
chad at Hugin ~/cprojects/ctesting $ ./trivial
chad at Hugin ~/cprojects/ctesting $ cat trivial.c
int main(int argc, char *argv[])
{
        return 0;
}

I checked dmd 2.050 at the same time just to make sure this isn't because I
changed my system config.  It still produces segfaulting executables.  I have
encountered another program that I didn't expect to segfault but did: the Gish
demo (http://www.chroniclogic.com/gish_download.htm).  I don't know if it's
related because the segfault is such a terribly vague error and I don't feel
like learning how to disassemble executables again right now :/  If someone
wants to point me in the right directions to do that though, I wouldn't mind.

So hey, maybe there is something special about my system that makes things
crashy, but it'd be nice if the D executables could run on my system without
crashing like all of the other executables on my system that don't crash.
