Code that should fail with /permissive-. Comments show the current output.
Option /permissive- from MSVC is described at:
<a href="https://docs.microsoft.com/en-us/cpp/build/reference/permissive-standards-conformance">https://docs.microsoft.com/en-us/cpp/build/reference/permissive-standards-conformance</a>
MSVC errors out on warnings that break conformance to a standard.
clang-cl generates the warnings, but it does not error out. It produces an
executable.
The excepted behavior is that the build should fail.
Please see attachment for an example.
Platform: Windows 10
Clang-cl version: 11.0.1
MSVC: 19.28.29336 for x64</pre>
