<pre>Thanks for the report. The situation here is a little complicated:
In ISO C++14 onwards, 0 cast to some other type is not a null pointer constant
any more, so cannot be implicitly converted to const char*.
This change was made in core issue 903
(<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#903">http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#903</a>), which was
moved in DR ("defect report") status, which means the intent is that it applies
retroactively to at least the prior standard. As a result, Clang applies this
change in C++11 onwards.
The extent to which other vendors track defect reports and apply them
retroactively is up to them, but this is intended behaviour in Clang.</pre>
