I did find something interesting (running on Ubuntu):

---------------------
rdmd> ./rdmd foo.d
rdmd>
rdmd> echo $?
245
rdmd> dmd foo.d
rdmd> ./foo
hello
Segmentation fault
rdmd> echo $?
139
---------------------

There's the 139 and 245 you were talking about. Looking at the source to rdmd:

private int run(string[] args, string output = null)
{
    import std.conv;
    yap(args.text);
    if (dryRun) return 0;

    File outputFile;
    if (output)
        outputFile = File(output, "wb");
    else
        outputFile = stdout;
    auto process = spawnProcess(args, stdin, outputFile);
    return process.wait();
}

so it must have something to do with spawnProcess() and wait().
