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.
