            Bug ID: 31598
           Summary: Clang-CL ICE with precompiled headers, export and
                    parameter default initialization
           Product: clang
           Version: 3.9
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: Driver
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

Using the 3.9.1 binary package for Windows from
http://releases.llvm.org/download.html and the following sources, I get an ICE.
It works with the MSVC CL.exe:

c:\dev\tmp>type source_file.cpp

#include "header_file.h"

BoolValue::BoolValue(bool b)
{

}

c:\dev\tmp>type header_file.h

#pragma once

struct __declspec(dllexport) BoolValue
{
    BoolValue(bool b = false);
};

c:\dev\tmp>"C:\Program Files\LLVM\msbuild-bin\CL.exe" /c /Ycheader_file.h /FI
header_file.h source_file.cpp
clang-cl.exe: error: clang frontend command failed due to signal (use -v to see
invocation)
clang version 3.9.1 (branches/release_39)
Target: x86_64-pc-windows-msvc
Thread model: posix



It also works if I remove the __declspec(dllexport) or if I remove the '=
false' from the header.
