           Summary: Segfault when trying to call a templated property with
                    inout.
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: ice
          Severity: regression
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com

Test case:

-----------------
struct S7424
{
     property inout(int) g()() inout
    {
        return 0;
    }
    void test()
    {
        int f = g;
    }
}
-----------------

The  property is optional. Compile with 'dmd -c bug7424.d'.

The expression 'this.g()' has a NULL 'type', so the statement at
expression.c:10112

        Type *t2 = e2->type->toBasetype();

caused SEGFAULT.

The regression is introduced in commit
1d4438f151143fcdcb807e257959dd1d588f9048.

Further test cases:

--------------------------------------------------
// Should compile:
struct S7424a
{
     property inout(int) g()() inout { return 0; }
    void test1() { int f = g; }
    void test2() const { int f = g; }
    void test3() immutable { int f = g; }
}
--------------------------------------------------
// Should fail:
struct S7424b
{
     property int g()() { return 0; }
    void test() const { int f = g; }
}

struct S7424c
{
     property int g()() { return 0; }
    void test() immutable { int f = g; }
}

struct S7424d
{
     property int g()() immutable { return 0; }
    void test() const { int f = g; }
}

struct S7424e
{
     property int g()() immutable { return 0; }
    void test() { int f = g; }
}

struct S7424f
{
     property int g()() shared { return 0; }
    void test() { int f = g; }
}

struct S7424g
{
     property int g()() { return 0; }
    void test() shared { int f = g; }
}
--------------------------------------------------
