<p class="MsoNormal" style="margin-left:36.0pt">That's pretty odd. Can you rule out for sure that the files aren't being written somewhere unexpected or that the other clang was built against different sources?<span style="font-size:12.0pt;mso-fareast-language:EN-IE"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Book Antiqua",serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Book Antiqua",serif">Yes you’re right, it appears to be in ‘</span><span style="font-size:12.0pt;font-family:"Courier New"">c:\tmp\foo-XXXXXX.opt.yaml</span><span style="font-size:12.0pt;font-family:"Book Antiqua",serif">’,
though on Linux it is located in ‘</span><span style="font-size:12.0pt;font-family:"Courier New"">./foo.opt.yaml</span><span style="font-size:12.0pt;font-family:"Book Antiqua",serif">’. The sources for my Linux and VS2015 builds are identical.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Book Antiqua",serif">So it would appear that the temporary files is being created but not finalised – probably a CLang driver issue. I’ll dig deeper and see where this is going wrong and I’ll
re-post this to CFE-Dev.<o:p></o:p></span></p>

Sounds like a bug (I've never tested on Windows). I suggest filing a bug report. Also, in general, you'll have better luck with frontend questions on cfe-dev.<br>
