            Bug ID: 38696
           Summary: Clang-CL freezes compiling C++ file with OpenMP
                    enabled
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW

Clang-CL freezes compiling the attached TexturePack.cpp file, but only with
OpenMP enabled. I'm using LLVM for Windows with clang 8.0.0 (trunk) and MSVC
2017 19.14.26433.

The attached archive has all the necessary source files. I also provide a
buildlog.txt and a Python script (run.py) which you can use to run the command
on your machine (adjusts some paths and sets up the environment for Clang-CL).

The script makes some assumptions, eg. on the Visual Studio 2017 version. You
may need to exchange the "Professional" in the vcvarsall string with whatever
VS version you are using. It also assume LLVM is installed under C:\Program
Files\LLVM.

This is my first time submitting a bug report to LLVM -- please let me know if
you need any more information.
