          Issue ID: 13874
           Summary: Invalid FunctionTypeOf segfault the compiler
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux

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== Process terminating with default action of signal 11 (SIGSEGV):
dumping core
==8964==  Access not within mapped region at address 0xFFE801F1C

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