<pre>Created <span class=""><a href="attachment.cgi?id=12600" name="attach_12600" title="Rejected code.">attachment 12600</a> <a href="attachment.cgi?id=12600&action=edit" title="Rejected code.">[details]</a></span>
Rejected code.
The attached code do not compile under clang 3.4-1ubuntu1.
$ clang file.cpp -std=c++11
file.cpp:20:5: error: call to 'operator*' is ambiguous
...
However, the code compiles if either:
- Lines 7-9 are removed.
- Lines 8 and 12 are replaced with "C< T >".
- operator* is replaced with operator/ in lines 9, 13 and 20.
- The code
template< typename T >
using Result = C< decltype( (*(T*)0) * (*(T*)0) ) >;
is inserted after the class definition, and lines 8 and 12 replaced with
"Result<T>".
Since this seems specific to operator*, I believe is a compiler bug.
