<pre>The following code causes a Windows hosted build of the compiler targeting
Windows to crash:
//===== test.cpp =====
void foo(int x) { }
void bar_d(int i) throw(double) { foo(i); }
typedef void (*vifunc)(int);
vifunc vitbl[] = { bar_d };
//====================
Compile the code with the command:
clang "-cc1" "-triple" "x86_64-pc-windows-msvc" "-emit-obj" "-main-file-name"
"test.cpp" "-target-cpu" "x86-64" "-fcxx-exceptions" "-fexceptions" "test.cpp"
And a debug build of the compiler will produce the following stack trace when
it crashes:

This crash started to happen with revision 231981, and I can reproduce it with
the newest build I have, 233744.</pre>
