<pre>If you try to profile an executable that was compiled with native clang on
Windows (even if it is linked with the MSVC linker) and you try to profile it
with instrumentation it will fail.
The error message indicates that the binary is not recognized.
It is really hard to research this problem but from what I found out, I believe
some pdb symbols are either wrong or incomplete.
This is basically a deal-breaker for choosing clang as an MSVC drop-in
replacement (although I would very much like to do so).</pre>
