          Issue ID: 13874
           Summary: Invalid FunctionTypeOf segfault the compiler
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: DMD
          Assignee: nobody puremagic.com
          Reporter: pro.mathias.lang gmail.com

The following code crashes the compiler:

````
import std.traits : FunctionTypeOf;
enum DummyEnum;
static assert(!is(FunctionTypeOf!DummyEnum));
````

% ./projects/dlang/dmd/src/dmd segv.d
[3]    8952 segmentation fault (core dumped)

Valgrind believes it's a stack overflow:

==8964== Stack overflow in thread 1: can't grow stack to 0xffe801f1c
==8964== 
==8964== Process terminating with default action of signal 11 (SIGSEGV):
dumping core
==8964==  Access not within mapped region at address 0xFFE801F1C
==8964==    at 0x411591: TypeEnum::getProperty(Loc, Identifier*, int) (in
/mnt/shared/projects/dlang/dmd/src/dmd)


Tested with dmd 2.066.1 & master (v2.067-devel-1b8db26).
