           Product: D
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: major

The code below will cause a segmentation fault when compiled.

class foo{this(){}}
typedef foo bar;

void main(){
        foo a;
        bar b;
        auto x = (a==b);
}

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
        {

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.
