          Priority: P2

struct A{
    struct{
        B b;
        C c;
    }
}
struct B{
    int i;
}
struct C{
    int j;
}

and DMD bombs out. Seems to be a forward referencing problem, as the AnonDeclaration's scope never gets set.

Okay, for some reason my test case doesn't seem to be working. I'm sure it was earlier, but I deleted the file, etc.

I can still get the segfault with my original (humongous) code, as well as a few others if the structs are rearranged a little. But I'm not whittling it down again.

Here it is if anyone cares:

http://personal.utulsa.edu/~ellery-newcomer/dxl.zip

unzip it and run dmd @kmd.

the problem file is src/dxl/read/biff/FilePassRecord.d

This is probably the same as bug 4543, which has a reduced test case.

There is no kmd file. Also this code seems to use Tango (dunno which version!). So it's not a usable test case. But I'm pretty sure this is the same as 4543. Reopen if you think it is not the same, and have some kind of usable test case.

I have little to no recollection of filing this isssue (and I agree it's pretty bad), but I don't think issue 4543 sounds like what this one was. I'll try digging things up this weekend. Sorry to waste your time, Don.

Rats. It looks like dxl.zip has been overwritten since I reported this. I guess we'll never know..
