Test cases:

-----------------------------------------------
class C7568 {}
struct S7568 { C7568 c; }
auto test7568a() { return [new C7568]; }
auto test7568b() { return S7568(new C7568); }

pragma(msg, test7568a());
pragma(msg, test7568b());
-----------------------------------------------

This will cause a segmentation fault:

    test.d(4): Error: C7568 class literals cannot be returned from CTFE
    Segmentation fault

This happens because an Expression* is assigned to the value 0x1, and the function 'argsToCBuffer' is trying to access the expression without first checking if the expression is a valid pointer.

The program should simply fail to compile, without the segfault.
