Please remember to assign keywords to bug reports.  To everybody reading this: Please look through issues you've reported and check for missing keywords.

The code should be accepted, but at least it's easy enough to convert the segfault into an error with line number:

e2ir.c line 3612.

        cdfrom = e1->type->isClassHandle();
+       if (!cdfrom){ error("ICE: Bugzilla 2346");      return e;}
        cdto   = t->isClassHandle();
        if (cdfrom->isInterfaceDeclaration()) //<------ it is segfaulting here
        {

Created an attachment (id=355)
 --> (http://d.puremagic.com/issues/attachment.cgi?id=355)
Work in progress: analogous to a single level B+Tree

Internal error: e2ir.c 4339

This is code that was compiling using
Digital Mars D Compiler v2.029
dmd -c -Dddocs chunkf.d
until I did a little bit of refactoring.

It's not clear to me how to reduce this and still retain the error, but if I
comment out lines 115-116,
        //foreach    (Wrd w;    freqWrd)
        //{    temp2 [w.name]    =    w.id;    }
then the error message goes away.  (Of course, it's useless for *my* purposes,
but I hope it narrows down what the error could be.)

Don't put any more work into it, Walter has fixed this bug in the next release.
