I'm having trouble getting a trivial d program working properly. I'm trying
with gdc both with the prebuild binaries downloaded from
http://downloads.sourceforge.net/dgcc/gdc-0.24-x86_64-linux-gnu-gcc-4.1.2.tar.bz2?modtime=1187745544&big_mirror=0
and with a version I built myself. I installed the prebuilt one in /usr/local.
For the one I built, I specified d version 2, a prefix in my home dir and
static and no shared options to allow it compile. I'm on fedora 9.

gdc compiles the program fine and it runs. As long as I enter words, it echos
them back. But when I hit ctrl + d to signal eof, it seg faults.

$ cat test.d
import std.stdio;

int main()
{
        char[] buf;
        while ((buf = readln()) != null)
                writef("%s", buf);
        return 0;
}

$ gdc -Wall -g test.d -o test

$ ./test
hello
hello
<I typed ctrl + d here.>
Segmentation fault

I'm not sure if this is the right place to report this. If somewhere else is
better, please let me know where.
