This code used to work up to version 2.031 without problems, since 2.032 it manages to crash dmd.

[CODE]
typedef byte[] Foo;

Foo bar;

foreach(value; bar){}
[/CODE]

There's a missing toBaseType() in the Foreach code which was introduced in
D2.032.

PATCH:
statement.c, line 1525, in ForeachStatement::semantic():
------
        Identifier *id = Lexer::uniqueId("__aggr");
        ExpInitializer *ie = new ExpInitializer(loc, new SliceExp(loc, aggr,
NULL, NULL));
-        VarDeclaration *tmp = new VarDeclaration(loc,
aggr->type->nextOf()->arrayOf(), id, ie);
+        VarDeclaration *tmp = new VarDeclaration(loc,
aggr->type->toBasetype()->nextOf()->arrayOf(), id, ie);

        Expression *tmp_length = new DotIdExp(loc, new VarExp(loc, tmp),
Id::length);

huh ? it is gone ? in dmd 2.032 - 2.039 it is certainly not, otherwise the compiler would complain using it (puting this crash aside). since when is typedef gone and why ?

whatever is meant by "typedef is gone" the compiler should not crash under any circumstance. feel free to change the keywords to ice-on-invalid if that is the actual case.
