          Issue ID: 15998
           Summary: Segmentation fault on const folding of arrays of
                    static arrays
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: timon.gehr at gmx.ch

The following code causes a segmentation fault in DMD 2.071.0.

immutable{
    string[2] foo=["",""];
    string[2][] bar=foo~baz;
}
auto baz(){
    immutable(string[2])[] r;
    return r;
}

No segmentation fault happens with DMD 2.060 (it incorrectly rejects the code
as invalid).

The example should compile.
