cat > bug.d << CODE
struct Foo
{
    int[int] tab;
}

Foo ctfe()
{
    Foo foo;
    foo.tab[0] = 0;
    return foo;
}

enum f = ctfe();
CODE

dmd -c bug

--------

The segfault happens during the hasNonConstPointers check for the enum initializer. At that point the tab field type is 'int' instead of 'int[int]'.

The type of the AA was set incorrectly. When expression is x[n]=y, type of the
AA
is x, not x[n].
