            Status: NEW
          Severity: normal
          Priority: P2

As discussed many moons ago, here:

http://forum.dlang.org/thread/j3gset$1s16$1@digitalmars.com?page=3#post-op.v01l4tgq1hx7vj:40biotronic-pc.lan

struct S {
    @disable this();
}

void main( ) {
    S[] a;
    a.length = 4;
}

The above code should not compile. Changing the length of an array like that (actually decreasing would be ok) should be a compile-time error, as those new elements cannot be properly constructed.

More like @disable this(); is completely broken for structs: bug# 7021

Indeed. Perhaps these two should be merged. I thought of them as two separate issues, but see now that might not be the case.
